Case studies testing some or most of the tools indicate that the authors are cautious, that the few larger companies that focus on the circular economy are unknown to the authors, or that the authors wish to take care of their own transition. The SLR revealed that 'regeneration' and 'exchange' are often not compatible with the tools from the ReSOLVE framework principles.

To9 achieve this purpose, it uses a systematic literature review (SLR) to synthesise information10 from several original studies and systematise the findings. SLR was also used to examine11 concepts that could be interpreted as synonyms for the main idea; it would be possible to add12 other synonyms to the list, but initial attempts did not help to increase the findings already13 identified. Case studies testing some or most of the tools indicate that the authors are cautious,14 that the few larger companies that focus on the circular economy are unknown to the authors,15 or that the authors wish to take care of their own transition. The SLR revealed that16 ‘regeneration’ and ‘exchange’ are often not compatible with the tools from the ReSOLVE17 framework principles.

Introduction24 Manuscript Click here to download Manuscript: Circular-business-model_RCRx.docx Click here to view linked References The circular economy (CE) clearly presents many challenges to traditional linear business25 models. The added focus on sustainability does not always help to solve the problems that the26 CE aims to address. A conceptualisation of the circular business model (CBM) is lacking in27 the academic literature. In fact, few authors have provided a clear CBM concept. Linder and28 Williander (2017, p. 2) defined a CBM as ‘a business model in which the conceptual logic for29 value creation is based on utilizing the economic value retained in products after use in the30 production of new offerings.’ Thus, a CBM implies a return flow to the producer from users,31 though there can be intermediaries between the two parties. The term CBM, therefore,32 overlaps with the concept of closed-loop supply chains, and always involves some ‘recycling’33 principles or strategies.34 Geissdoerfer et al. (2018) identified the CBM as a subcategory of the sustainable business35 model and characterised CBMs as creating sustainable value, employing proactive multi-36 stakeholder management, and having a long-term perspective, as well as closing, slowing,37 narrowing, intensifying, and dematerialising resource loops. Geissdoerfer et al. (2017)38 searched for similarities and differences between sustainability and the CE. They also39 summarised warnings about the negative impacts of the CE: a) circular systems will incur40 specific costs; b) the necessity of coping with the technical impossibility of really closing the41 circle; and c) recycling will be accompanied by growing demands on energy; the negative42 impact of this demand will be higher, especially in the form of the greenhouse gas emissions,43 than the overall environmental effect of acquiring the material from conventional sources44 such as mining.45 Despite the lack of conceptualisation, the topic of CBM has attracted scholarly attention, since46 it has become clear that the shift to a CE demands an understanding of how companies can47 introduce circularity into their business models (Lewandowski, 2016). This means a change in48 several building blocks of a company’s business model, particularly value propositions,49 channels, resources, and activities; it may mean changes in the whole model as well as the50 development of a new one(s). To this point, Nuβholz (2017) argued that ‘the key difference of51 circular business model elements, compared to linear ones, appears to be the embeddedness of52 a circular strategy in the offer, which can alter material flows.’53 The implementation of CE principles would affect all the building blocks of the business54 model framework, since CE principles change the logic behind value creation, delivery, and55 capture. Other than remanufacturing and recycling and other value recovery practices (e.g.56 Verstrepen et al., 2007), four terms are most often associated with the CE and CBM. To a57 certain extent, they reflect the contents of the ReSOLVE framework: product service systems58 (PSS), consumer (customer) acceptance, sharing (and collaborative economy), and internet-59 of-things (IoT) or industry 4.0. These terms reflect, more or less, the specific features of60 CBMs. There are many interdependencies among the contents of those terms; however, they61 can exist independently in practice. For instance, Kjaer et al. (2018, p. 666) argued that ‘PSS62 are often mentioned as a means to enable a transition from a linear to a circular economy.’63 The provision of services within PSS is more and more dependent on the different64 functionalities enabled by industry 4.0 and IoT (Bressanelli et al., 2017). Use-oriented PSSs65 are often related to sharing and collaboration business models (Annarelli et al., 2016).66 The main goal of this article is to map the current knowledge about CBMs and tools for the67 transition. To achieve this goal, we used a systematic literature review (SLR) and68 systematised the results according to several sets of criteria: business model content, i.e.69 components or elements of business models; the ReSOLVE framework combined with six70 business strategies for slowing and closing loops, as suggested by Bocken et al. (2016), and71 the strategy for narrowing the loops; and extended boundaries of analysis and adapted72 approach types and types of work (Pieroni et al., 2019).73 2. Existing reviews on circular business models and tools for the transition74 A comprehensive review aiming to systematise the state-of-the-art of available approaches75 supporting a circular-oriented or sustainability-oriented business model innovation process76 was presented by Pieroni et al. (2019). The approaches are systematised in three streams. The77 first stream, based on Teece’s dynamic capabilities-based view, is divided into three78 categories: (1) sensing: approaches that help to identify opportunities and generate new79 business model ideas; (2) seizing: approaches that systematically design and test new business80 model concepts or configurations; and (3) transforming: approaches that help to build new81 competencies and implement organisational renewal. The second stream, based on three82 business model innovation characteristics, includes boundaries of analysis (organisational,83 inter-organisational, and societal), abstraction level (aggregated, moderated aggregated, and84 details), and time-related view (static and dynamic). The third stream, based on the approach85 type, covers conceptual framework, guideline manuals, process model, cards/serious game,86 visualisation tools, and simulator/software.87 Singh et al. (2019) identified 145 best practices or approaches to resource efficiency and the88 CE in order to reduce energy and material demand in the product sectors. Approaches include89 durable product design, enhanced repair and upgrade services, and product take-back models;90 the approaches provide important insights into planning more circular business to resource91 efficiency. Lieder and Rashid (2016) summarise the outcomes of their review of the CE92 categorised according to the three perspectives: resource scarcity, environmental impact, and93 economic benefits. Frameworks, tools, models, and methods for decision making according to94 these perspectives and selected based on their possible applicability for the transition and shift95 towards the CE, in general, are introduced in Table 1. They differ in depth and breadth, focus,96 and areas of interest, and they range from very general and probably rather abstract to very97 narrow and specific.98 Pieroni et al. (2018) conducted a comprehensive review of the literature with the purpose of99 exploring the existing methods aimed at supporting the development of CBMs and their level100 of consideration of and/or integration with product design processes. They identified 10101 methods that fulfil more or less the integration of CBM development and product design. The102 authors concluded that the weaknesses of the methods from the list reside in their relatively103 high levels of abstraction, a lack of ‘how-to’ guidance or methodological support, and the lack104 of a more holistic perspective and a connection to commercialisation and operationalisation.105 3. Methodology106 According to Denyer and Tranfield (2009, p. 672), SLR is ‘a specific methodology that107 locates existing studies, selects and evaluates contributions, analyses and synthesizes data,108 and reports the evidence in such a way that allows reasonably clear conclusions to be reached109 about what is and is not known.’ SLR comprehensively identifies, appraises, and synthesises110 all the relevant studies on a specific topic and helps to identify gaps and diversity in current111 research (Petticrew and Roberts, 2006; Correia et al., 2017). Essentially, SLR aims to112 synthesise the knowledge from multiple original studies.113 No unified process for SLR exists; authors differ in the number of steps and in the details of114 each step. For this paper, based on Correia et al. (2017) we defined five phases: (1) problem115 formulation and question identification; (2) literature search; (3) evaluation of research; (4)116 research analysis and interpretation; and (5) presentation of results. This set of phases117 represents a process that is replicable, transparent, objective, unbiased, and rigorous.118 The term ‘tools’ is used in this text for simplification when dealing with the purpose of the119 SLR. The SLR concerns tools that may help companies, and specifically both demonstrators,120 in their move towards CBM. As Geissdoerfer et al. (2017) noted in their comparison of121 sustainability and CE, no clear and unified opinion on a clear dividing line between these two122 approaches exists; nevertheless this report concentrates on the tools that were invented,123 developed, and created primarily for the CE.124 This approach enables a focus on the potential specificities of the tools. However, it also can125 eliminate some important and beneficial approaches that have not been presented as more126 general or applicable also for the CE. Thus this SLR considers tools and we also searched for127 the concepts that can be understood as synonyms for the core idea. This means that128 frameworks, methods, models and modelling, approaches, strategies, schemes, patterns, and129 roadmaps entered the review. We are aware that even more synonyms could be added to the130 list, such as tactics, ways, procedures, mechanisms, and practices, but our initial attempts did131 not expand the existing results.132 We used innovation and change as well as transformation, transition, shift, and adaptation in133 the search in order to cover as many as possible terms for the process from an existing134 business model to a circular one or to a more circular one. We omitted the term improvement,135 which – despite its importance – does not reflect the real procedural needs of both136 demonstrators. Improvement is a natural part of most of the tools we detected. For137 simplification, we use the term transition to represents all possible synonyms in the following138 text.139 3.1. All synonyms have been taken into account during the documents review140 There are several reasons that an SLR on the tools for companies that are moving towards a141 CE is needed. First, the tools that are available for the change or innovation of linear business142 models may have limited value for the far more complex solutions in the CE (Nuβholz, 2017).143 Second, even recent literature indicates and stresses the lack of tools that can either support144 particularly large and traditional manufacturing businesses in increasing their understanding145 of the consequences of CE business model transitions (Lieder et al., 2017) or enable and146 accelerate transition as well as identify and tap the potentials of transition at the company,147 inter-company, and/or whole network level (Lieder and Rashid, 2016; Leising et al., 2018).148 The body of knowledge about tools for the transition of business models towards circularity is149 immature; it is mostly conceptual and covers individual company business models, mostly150 niche market pioneers and rarely (if at all) mass-market incumbents and relevant network151 stakeholders of the whole ecosystem (Diaz Lopez et al., 2019; Parida and Wincent, 2019).152 Parida and Wincent (2019) also highlighted that most existing research focuses on the153 business model itself rather than on the process of transformation and offers a static view of a154 reality that is actually very complex and dynamic.155 One supporting argument may be that the existing literature on the CE has been developed156 outside of management and organisational theory (Lahti et al., 2018). However, management157 and organisational theory is built largely on the investigation of the practices (of the158 management processes, managerial mindset, cognitive schemes, and conceptual159 representations); very few companies have yet managed the transformation towards a circular160 business (Lieder and Rashid, 2016; Lahti et al., 2018; Parida and Wincent, 2019).161 Finally, there has not been an SLR mapping the tools for the transition, transformation, or162 adaptation of business models for the CE. Table 2 show the strings used for the search in three163 databases (Web of Science – WoS, Scopus, and Proquest), the types of documents, and the164 results.165 The same search string was used in Google Scholar. The search revealed 47,000 documents166 (from this database, only the first 100 documents were analysed for the purposes of this167 review). The first screening was based on the titles, abstracts, and keywords to assess the168 compliance with the research aim and research question. After that screening, 85 documents169 from WoS and Scopus remained for further analysis, but 8 documents had to be excluded170 because the text was not available. In the next step, 77 documents were subjected to the171 content analysis of the full text. From Proquest, 22 unique documents enriched the outputs of172 the initial review of titles, keywords, and abstracts. Of those 22 documents, 12 documents173 were added into the sample for the next step. The Google Scholar search generated 11174 documents; however, after the abstract scanning, only 6 remained for the whole text review.175 During the review of the documents, a snowball technique was adopted; through the citations176 made by the authors of the included studies, a further 9 documents were added to the final177 sample. This number includes theses and tools designed by some organisations and178 institutions.179 Finally, 104 documents were examined thoroughly in accordance with the research purpose.180 This examination helped to exclude 69 documents that – despite promising abstracts, titles,181 and keywords – were irrelevant for the purpose of the SLR, because they did not contain any182 transition tools, or the tools were extremely simple, or the document quality was rather low,183 or their character was too speculative and the reasoning was insufficiently relevant. In the184 end, only 35 documents and almost all of the academic articles involved, to some extent, tools185 that we considered relevant. This finding confirms conclusions from the literature about a186 sizable deficiency in the methodological support for CE transition. During the SLR, additional187 articles were found in the literature for designing CBMs that contained a review of existing188 tools. The next subchapter introduces this overview briefly.189 4. Results of systematic literature review190 In order to provide an empirical illustration of our proposed methodology, we arranged the191 following classification according to the business model components: value proposition (VP),192 customer/stakeholder segment (C/SS), customer/stakeholder relationships (C/SR), channels193 (CH), key processes (KP), key resources (KR), key partners (KP), cost structure and negative194 impacts (CS+NI), revenue streams and positive impacts (RS+PI), or whole model (WM).195 These classifications help to understand the importance of the specific features of the196 components and the ways they can be evaluated, changed, created, designed, or developed as197 new features into a circular model with concrete tool for CBM innovation.198 4.1. Tools for transition199 The ReSOLVE framework, circular loops, and business strategies help to classify tools to be200 adopted as suitable for the specific circular business target or orientation. The following201 abbreviations will be used in the text: regenerate (R), share (S), optimise (O), loop (L),202 virtualise (V) and exchange (E); and slowing and specific strategies/value recovery processes203 for slowing (Sl –xxx), closing (C -xxx), and narrowing (N). The extended boundaries204 represent specific business functions (BF), organisation (O), network (N), (eco)system (eS)205 and society (S) and assigning the ‘tool’ to some of these categories makes it possible to see206 the level of complexity regarding the organisation of processes within a circular business.207 The last approach types are adapted into the: conceptual framework (CF), conceptual method208 (CM), guideline (G), process (P), process model/method (PM), game (Gm), visualisation tool209 (VT), software simulation (SS), and (statistical) mathematical modelling (MM). The role of210 this categorisation is only in offering a better overview and for the evaluation of the211 applicability in concrete situations (considering, for instance, time or competencies or other212 available resources). Type of work is purely theoretical (conceptual) (T), theoretical and213 tested in ‘laboratory conditions’ (TTL), theoretical and tested or verified in a real environment214 (TTR). No purely empirical tool was found in the literature.215 The last criterion evaluates the maturity of the tool based on the practical application and216 verification. We use a scale from 1 to 5 from the least mature (1) to the most mature tool (5),217 being fully aware of the very subjective nature of the evaluation. Abbreviations are shown in218 brackets to mean that their indication is not of 100% value. Most of the existing tools are219 conceptual, and they exist in the form of a proposal, despite the fact that some of them have220 been tested in a ‘laboratory’ environment or during interviews with practitioners. Only a few221 were tested in a more complex form. The results are shown in Table 3.222 4.2. Value proposition (VP)223 The checklist can be used to evaluate the promise fulfilment and relationship maintenance224 with consumers in the CE. The main drivers (main factors that influence the behaviour of225 three CE solutions) can serve as a checklist for the design of the value proposition of the226 access-based PSS and for the consumer segmentation (Camacho-Otero et al., 2018). The227 framework can be applied at multiple points while designing new products ‘to increase the228 likelihood that “emotion building” features are integrated into an end product’ and so to229 support prolonging the life of products instead of promoting or being passive within a230 throwaway society (Haines-Gadd et al., 2018). With nine themes, the authors developed 38231 strategies incorporated into the product design.232 A choice-based method conjoint analysis is beneficial for breaking down CE value233 propositions and identifying the extent to which particular service-related attributes and234 product-related attributes contribute to overall customer utility (Lieder et al., 2018). The235 framework that makes it possible to design products and services to encourage desired236 circular behaviours is based on the design for behaviour change and the behaviour change237 wheel (Wastling et al., 2017).238 4.3. Customer/stakeholder segment (C/SS)239 The checklist of the main factors that influence perception and acceptance of the use of loop240 solutions using what is used in the VP component (Camacho-Otero et al., 2018). Emotional241 Durability Design Nine uses the same framework with VP applicable for characterising242 segments (Haines-Gadd et al., 2018).243 4.4. Customer/stakeholder relationship (C/SR)244 The checklist used in VP can also be used to evaluate the promise fulfilment and relationship245 maintenance with consumers in the CE (especially in the access-based PSS) (Camacho-Otero246 et al., 2018). Emotional Durability Design Nine with VP is applicable for building and247 maintaining relationships (Haines-Gadd et al., 2018). The model may identify and influence248 ‘pro-circular behaviours’ of customers (Muranko et al., 2018).249 This tool is for creating future product strategies for CE PSS. The tool visualises the points250 within a product’s lifecycle at which stakeholders are able to intervene in the product’s251 expected journey. CIM contains concentric rings that make it possible to indicate the degree252 to which an organisation is able to control consumer interventions, with decreasing ability253 moving away from the centre of the map. At the narrowest level of detail, CIM offers 18254 discrete phases of intervention. The tool can also be used for portraying how a particular255 product lifecycle moves in and out of an organisation’s control (Sinclair et al., 2018).256 4.5. Key resources (KR)257 Asif et al. (2018) proposed an infrastructure for access-based PSS for the washing machine258 that incorporates various features and properties (e.g. predictive maintenance, ticketing, etc.).259 A simple framework/checklist for evaluating two categories of digital technologies (IoT and260 big data and analytics) as the enablers of increasing resource efficiencies, extending the261 lifespan and closing the loop (Bressanelli et al., 2018). The Circular Material Library should262 work as a tool to support industrial symbiosis, open to the different stakeholders and to263 promote the use of recycled materials (Virtanen et al., 2017).264 4.6. Key partners (KP)265 Franciosi et al. (2017) suggest that a periodic preventive maintenance model establishes the266 optimal maintenance period for each system component, minimising conventional,267 environmental, and social costs generated by maintenance interventions and making it268 possible to choose the most suitable parts from a sustainability perspective. A simple checklist269 with the summarised key processes enabling closing and slowing the loops (and to some270 extent also narrowing the loops) (Mestre and Cooper, 2017). This is a proposal of hybrid271 systems called an ‘Upgradable Product-Service System (Up-PSS)’ that combines272 upgradability with optimised maintenance, valorisation of end-of-life parts and with the273 servitisation of the offer. The system can be used as a checklist for practices within PSS when274 upgrading is needed and as a typology of upgrades (Pialot et al., 2017).275 4.7. Cost structure and negative impacts (CS+ NI)276 Aguilar-Hernandéz et al. (2018) explained environmentally extended input-output analysis277 (EEIOA) for circularity interventions, covering the main benefits and problems with the278 input-output analysis for four circularity scenarios and presenting the process of using this279 method for the CE. The multi-method simulation technique for the economic and280 environmental performance of the circular product system is a comprehensive agent-based281 model and a multi-method-based simulation technique that incorporates various categories of282 inputs from the external and internal environment, causalities, and inter-dependencies to283 measure and evaluate different economic and environmental dimensions of the circular284 product service system performance (Asif et al., 2016). Guidelines for the process of LCA285 consider the specificities of three different PSS. The guidelines reflect relatively detailed286 inputs and different requirements from the actors (Kjaer et al., 2018).287 This is a simple analytical tool allowing manufacturers to quickly evaluate and compare the288 potential attractiveness of a circular business model – selling and leasing. ‘The tool shows289 which parameters drive profit and TCO and permits an easy sensitivity analysis’ (van Loon et290 al., 2017). The framework consists of an environmental value propositions table (EVPT) and291 a step-by-step approach towards an evaluation process; the framework can be used for292 planning and designing new CE business models or for assessing the environmental benefits293 and the contribution to sustainability; the framework, contents of the EVPT, and the approach294 has been tested with one recycling company and two real estate companies (one is the real295 estate company Homie) (Manninen et al., 2018).296 A list of several methods and tools for measuring environmental impacts described by Pajula297 et al. (2017) includes the life cycle assessment (LCA), carbon footprint measurement, tracking298 of greenhouse gas (GHG) emissions, the water footprint – a tool for assessing potential water-299 specific environmental impacts of water use associated with a product, process, or300 organisation, and the handprint – a measurement of the positive changes of actions and the301 beneficial impacts created within the life cycle of products, services, processes, companies,302 organisations, or individuals.303 4.8. Whole circular model (WM)304 The framework may be suitable for evaluating the transition towards circularity, as it305 considers macro, meso, and micro environments (Antikainen and Valkokari, 2016).306 According to Bocken et al. (2018), the purpose of the cycle is to help in designing or307 redesigning for any sustainability-oriented business models that utilise IoT strategies. The308 framework combines a level of control between product and user, sustainable design309 strategies, IoT strategies (capabilities), and other strategies. This is a relatively comprehensive310 tool for designing new and redesigning existing business models, both for sustainability and311 circularity (Bocken et al., 2019a). Its comprehensiveness lies in many aspects the model312 involves and in the mutual linkages.313 The framework combines four IoT strategies (monitoring, control, optimisation, and314 autonomy) connected to/focused on either user or product and other non-IoT strategies (not315 listed) with seven sustainable design strategies considering the level of control (with the user316 or product) (Bocken et al., 2019b). The roadmap contains four phases with individual317 objectives for every phase, a checklist for the important issues in every phase, and a checklist318 of the key activities and the expected outcome (Frishamar and Parida, 2019). The UIW-319 framework is used as a template for system implementations of practices to develop a product320 service system and to support a systematic adaptation to changing needs by developing321 business models and technologies to support collaborative efforts (Granholm and Grösser,322 2017).323 This is a proposal of a conceptual framework for circular business network governance with324 some roots in the balanced scorecard method (Janssen and Stel, 2017). It is a brief proposal to325 use the cascading of materials in product life management (Kalverkamp et al., 2017). The tool326 or framework consists of the following building blocks: visions, actor learning, network327 dynamics, and business model innovation. The tool is suitable for managing key processes328 and activities, key partner relationships and mutual value creation, delivery, and capture in329 inter-organisational, network, or whole social system setting (Leising et al., 2018).330 The model and tool help to identify proper marketing and pricing strategies to obtain best fit331 demand behaviour (Lieder et al., 2017). The approach integrates socio-demographic and332 buying behaviour factors of customers (relative preferences of product attribute prices,333 environmental friendliness, and service-orientation), product utility functions, social network334 structures, and inter-agent marketing communication in order to comprehensively describe335 behaviour at the individual customer level. The BECE framework is also a method and336 methodology that integrates the backcasting strategic planning approach with the process337 design in the framework of a circular economy (Mendoza et al., 2017). This means that three338 CE principles, the ReSOLVE framework with added action IMPLEMENT and developed339 individual actions with iReSOLVE, and four basic CE frameworks create the playground to340 develop a circular business model.341 Mentink (2014) suggested the method and methodology to develop a circular business model.342 Nußholz (2017) provided a circular business model mapping tool that can help: a) to identify343 which interventions are used and which are not; a holistic overview on possible interventions344 could indicate opportunities to potentially capture more of the embedded value and organise345 value-adding activities; b) to examine whether the configuration of business model elements346 is suitable for efficiently supporting the additional cycles, such as whether value propositions347 are compelling for users in additional cycles or whether key resources and capabilities are348 present to manage the different cycles; c) to unravel a larger variety of phenomena compared349 to the traditional business model canvas, e.g. key partners, costs, and revenues for each cycle;350 and d) to show interdependencies between the interventions and how shaping business model351 elements in one intervention enables value creation from other interventions.352 The process model of ecosystem transformation towards a CE paradigm contains two steps353 with individual activities: ecosystem readiness assessment and ecosystem orchestration354 mechanisms (Parida et al., 2019). The methodology includes the evaluation tool for five355 different values created (and captured) in CBM, a visual tool, and the value metric checklist.356 ‘The value circle evaluation scheme assists companies in operating their CBM through an357 improved understanding of their potential to create value, from a multi-stakeholder358 perspective’ (Ritika, 2017).359 4.9. Retention streams, benefits, positive impacts360 Tools for revenue streams or benefits are almost non-existent. This might be due to the early361 stage of existing circular businesses or due to the conscious or unknown problems with362 capturing intangible benefits, which is probably more typical for circular business in the early363 period. The same situation is with segments (either customers or other relevant stakeholders).364 Only two tools fall into that component. The article by Chamberlin and Boks (2018) was not365 included as it does not contain any tool, even in the form of a checklist. ‘Soft tools’ prevail.366 This is not negative, as transformation or transition of the social system as a business requires367 soft tools.368 Aguilar-Hernandéz et al. (2018) used environmentally extended input-output analysis369 (EEIOA) for circularity interventions that can apply also for revenue streams and benefits.370 The two-stage dismantling planning method considers both preserving functional value of371 components and increasing profitability by applying suitable dismantling technologies (Cong372 et al., 2017). In this paper, disassembly is defined as preservative disassembly, which means373 that components are kept intact during disassembly.374 Nevertheless, softness could be in more harmony with more complex elaboration. As evident375 from the Table 3, frameworks represent the majority of tools and a very big share of them are376 really only outlines of real frameworks. The case studies through which some or most of the377 tools were tested show that the authors are probably cautious or those few bigger companies378 that turn their attention towards the CE are either not known to the authors or they want to379 take care for the transition themselves. In most cases, small companies and/or start-ups380 cooperated in the research.381 5. Discussion382 The overview shows that the ReSOLVE framework principles of ‘regenerate’ and ‘exchange’383 are not often equipped with tools. There are basically no guidelines and only few process384 models or methods exist. One comment should be added here – there are several tools and385 toolkits in the form of games, including online games, but these are only sporadically studied386 in the literature. There are almost no tools that could be used for the IoT or cloud387 manufacturing and IT platform based business models.388 Based on the review, several tools seem to be appropriate for both demonstrators.389 Experimentation (Bocken et al., 2019a) with relatively mature methodology is very effective390 for building and maintaining the organisational and inter-organisational culture and pro391 circular commitment and enthusiasm. Experimentation and other tools that involve more392 stakeholders and support sharing, have mutual goals and views, and open the space for mutual393 strategies play a pivotal role in any change management. The BECE framework, a process394 model for ecosystem transformation, and Emotional Durability Design Nine can also be very395 beneficial for such social movements.396 The only problem is that both demonstrators are from global mass-market manufacturing and397 existing experimentation and other tools that help to connect different stakeholders in a one-398 time window are very challenging if not impossible to apply. Simulation (mathematical or399 statistical) tools are from the other end of the spectrum, but necessary for large global400 enterprises with mass production. Another example is visualisation, especially in complex and401 dynamic environments. Visualisation tools are helpful in any case. The SLR did not detect402 any special tool for one of the demonstrators and their business, although some tools seem to403 be focused on consumers and mass consumer goods. The scarcity of tools for logistics and404 supply chains and for digital infrastructure management is somewhat surprising.405 6. Conclusion406 The review of CBMs reveals that there are still many unknown areas, or insufficiently known407 issues. Case studies mapping CBM development, implementation, and testing of large408 companies for several years are almost non-existent. There is a lack of a more complex409 understanding of how CBMs of large companies work and of the circumstances for the410 concrete functioning. The ownership question must be investigated more.411 Our results show that there is no transition device that is truly suitable for all types of testing412 instruments. More testing and developing of CBMs and tools for transition are needed. This413 paper confirms that SLR has not been able to design and test business model concepts or414 configurations systematically.415 The method we developed, based on the review of several tools, looks useful for both416 demonstrators in building and maintaining the organisational and inter-organisational culture417 and pro-circular commitment and enthusiasm. We understand that problems arise from the418 growth of mass markets worldwide, and current research and other methods that connect419 different actors are difficult to introduce.420 A new issue is also emerging for empirical streams of scientific discourse. It is necessary to421 evaluate short-term and long-term outputs, outcomes, and results of implementing circular422 business cycles and tools for transition. There are some conventional methods such as423 correlation and regression analysis using big data or large firm datasets, or new methods such424 as randomised quasi experimental design.425 Some methodological challenges must be addressed, particularly in the fields of social426 sciences such as economics and public policy. There will be a strong demand for new427 methodological approaches to correct effect estimations, solutions for endogeneity, and428 external validity problems of empirical analysis. Our review focused primarily on CBMs, but429 the issues of public policy, institutional environment, taxation, and incentive mechanism430 design remain important. Both practice and research are challenged to gain deeper and431 broader insights into the business life in a CE.432 Acknowledgement433 This work was supported by the European Research Framework H2020 research project434 Resource-efficient Circular Product-Service Systems (ReCiPSS).435 436 References437 Aguilar-Hernandez, G.A., Sigüenza-Sanchez, C.P., Donati, F., Rodrigues, J.F.D., Tukker, A.,438 2018.
