2.1. Twin Transition: Digital Transition and Sustainability
Sustainability is a crucial evolution path for companies in the modern economy [
3]. Recently, there has been increasing pressure on companies to cope with the changing and uncertain conditions in the market [
24]. Companies face several sources of market turbulence, e.g., globalization, new rules for environment protection, requesting quality standards, and rapid technological advancement [
24]. Therefore, companies need to invest in and prioritize sustainability to create value [
1]. Sustainability has been characterized as well-adjusted incorporation of human activities’ social, environmental, and economic performance to benefit current and future generations through a circular economy [
25]. Environmental sustainability corresponds to simultaneously seeking human well-being, protecting needed resources, and ensuring that waste from human activities does not expand [
26]. Yacob et al. [
27] described sustainable green practices as “embrace the use of eco-friendly design, raw materials, packaging, distribution and even re-use/retreatment after the useful life of a product. It describes practices throughout the manufacturing process that are not harmful to the environment” (p. 3). Social sustainability is the ability of a company to ensure that every individual is treated equitably, and economic sustainability ensures continuously generating profit, welfare, and wealth while respecting the environment [
28]. Sustainability can also be considered in developing business models that are environmentally and socially sustainable [
22,
29]. A sustainable business model can help companies beyond the essential reduction of waste, energy, and material consumption but also create financial and social values, mitigate risk, and improve resilience [
30].
SMEs, in general, may have internal barriers to environmental sustainability commitments, such as having a lower level of ecological awareness and resources than larger companies and marking their environmental impact as insignificant [
3]. Additionally, SMEs rarely refer to sustainability for improving their relationships with their customers or other stakeholders [
3]. Neri et al. [
31] summarized barriers to adopting sustainability for SMEs in the manufacturing industry into external and internal barriers. The external barriers include regulatory issues (legal requirements, bureaucracy, lack of incentives, and policy distortion), support (lack of external technical support, lack of consultancy), and market issues (customer not ready/lack of demand, uncertainty of future trend, distortion of price). Internal barriers are characterized as organization (lack of time, lack of staff, resistance to change/inertia, attitude/other priorities, communication, workplace and task, organizational system), management behavior (commitment/awareness and expertise), workers behavior (not trained/skilled, awareness, not involved, and incorrect behavior), information (lack of information and trustworthiness of information), innovation, and economics (limited access to capital, hidden costs, risk, investment cost, and pay-back time) [
31]. They found that the external barrier regulatory issues and the internal barriers organization and economics are the main barriers in a sample of 26 SMEs in the manufacturing industry in Germany and Italy.
In recent years, significant technological developments have triggered an evolution in the digitalization of society and business [
32]. This evolution resulted in an effective digital transformation affecting traditional roles and business models [
33]. Vial [
7] defined digital transformation as “a process that aims to improve an entity by triggering significant changes to its properties through combinations of information, computing, communication, and connectivity technologies” (p. 121). Digital transformation is not just about using individual technologies to improve operations, but is instead about aiming to transform the business using digital technologies [
6]. The ongoing digital transformation can open up new opportunities to develop new digital products and services, digital business processes, or digital business models for organizations [
8]. Digital transformation can enhance commitment to sustainability by transforming the conventional business with improved transparency, flexibility, agility, and customer relationships, reducing cost and energy consumption and improving overall efficiency and productivity [
3,
34,
35]. However, such a twin transition [
15,
36] towards using digital technologies and, at the same time, committing the whole organization to sustainability can create new challenges for SMEs [
3]. Kumar et al. [
4] identified 15 challenges affecting the adoption of digital technologies and I4.0 in SMEs for sustainable value creation. The challenges of adopting I4.0 technologies for sustainability are summarized as (1) awareness about I4.0 contributions to sustainable production, (2) lack of management support, (3) high initial cost of technology adoption, (4) lack of funds for investment, (5) low awareness about government policies for I4.0 and sustainability, (6) low dedicated resources for research & development, (7) required long term planning on the adoption of I4.0 technologies for ethical and sustainable operations, (8) motivations from customers, (9) IT-based infrastructure, (10) trained workforce for sustainable production I4.0 technologies, (11) required collaboration among supply chain partners, (12) fear of job loss or decrease of the workforce, (13) fear of I4.0 technological failure, (14) lack of alternative solutions in case of technological breakdown, and (15) fear of uncertainty in demand because of market disruptions [
4]. The rather technology-focused Industry 4.0 is currently being taken further to the ambitious concept of Industry 5.0 [
11,
12], focusing more on societal and ecological aspects, increasing the pressure on the manufacturing industry to invest in sustainable and resilient development with an even broader perspective, taking even more aspects into account.
Kumar et al. [
4] mentioned the lack of coordination and collaboration among supply chain partners as a challenge. However, although collaboration can be challenging, it can help SMEs overcome some challenges of adopting digital technologies. According to Kane et al. [
6], collaboration is a part of the digital transformation culture in digitally mature companies. We further discuss the importance of collaboration in the following section.
2.2. Collaboration for Sustainability
Collaboration can correspond to a durable and profound relationship between separated groups or organizations to achieve a mutual purpose [
37]. Patel et al. [
38] defined collaboration as follows: “Collaboration involves two or more people engaged in an interaction with each other, within a single episode or series of episodes, working towards a common goal” (p.1). In another definition by Hartono & Holsapple [
39], collaboration among business partners is “an interactive, constructive, and knowledge-based process, involving multiple autonomous and voluntary participants employing complementary skills and assets, with a collective objective of achieving an outcome beyond what the participants’ capacity and willingness would allow them to individually accomplish” (p. 20).
Establishing collaborative relationships with other companies can help SMEs strengthen their market position or exploit new opportunities [
40]. “Collaborative” refers to a set of processes planned to create harmony among parties who may disagree about the issue [
37]. Collaboration enables companies to access the resources and capacities of their collaborative partners that they may lack in-house [
41]. Furthermore, companies can benefit from inter-organizational collaboration to reinforce skills, mitigate resource challenges, share knowledge, foster innovation, and explore new business channels or exploit existing channels [
42]. Two primary outcomes for inter-organizational collaboration discussed in the literature are mainly innovation and performance [
43], where innovation outcomes differ in product, process, service, marketing, and organizational innovation. Performance outcomes include survival, competitive advantages, sales growth, and profitability [
43].
Sustainability is not discussed directly in the summarized outcome of the collaboration by Zahoor and Al-Tabbaa [
43]. In fact, in previous literature, collaboration for sustainability and the circular economy has been a somewhat neglected field [
44]. Nevertheless, environmental and social sustainability can be viewed from innovation and performance outcomes perspectives. Green product and process innovation are two main topics in literature considering sustainability as an innovation outcome. Green product innovation aims to mitigate environmental impacts in a product’s life cycle and satisfy customer needs by creating new products or improving existing products [
45]. Furthermore, green product innovation includes using nontoxic and biodegradable materials in product design, improving the durability and recyclability of products, and modifying product design to reduce energy consumption during usage [
45]. Green process innovation aims to reduce energy and resource consumption and use pollution-control equipment, recycled material, and environmentally friendly technologies [
45]. Collaborative circular-oriented innovation is an emerging area of research in sustainable-oriented innovation that requires a high level of collaboration among collaborative partners [
44,
46]. The need for collaboration can increase when a company’s strategy toward sustainability transfers from a product focus and operational optimization to organizational transformation and system building for positive social changes [
46].
Brown et al. [
44] defined the collaborative process as “the purposeful decisions and actions within and between organizations and the collaborative network of organizations engaged in this process” (p. 2). According to Brown et al. [
44], it has the following phases:
Identify the need and articulate the intent to collaborate
Identify and select partners
Align partners on a shared purpose
Develop structural and procedural governance
Define a collaborative value capture mode
In comparison, Reilly [
37] defined similar phases of identification path, formation, implementation, engagement or maintenance, resolution, and evolution for a collaborative path. We defined the phases of a collaborative process based on the discussed phases in Reilly’s [
37] and Brown et al. [
44] research as follows:
Identify the need for collaboration
Identify and select partners
Set up a collaborative strategy development and collaborative actions
Define collaboration resolution and collaboration evolution
The above-mentioned collaborative process descriptions do not explicitly address sustainability. However, sustainability aspects can be regarded from a broad perspective and on all levels of the collaborative process. Sustainability can be seen as a critical value that can be achieved by collaboration in a value constellation. Moreover, a collaborative process among different actors of the value constellation can be perceived from a sustainability and resilience perspective [
24]. Notably, the partner selection can be a delicate issue, and specifically which criteria to use. This has been widely discussed in the literature, mainly with regards to collaboration type, e.g., joint venture or strategic alliance (c.f. e.g., [
47,
48,
49,
50]). Strategic supplier selection for sustainability and resilience has come into focus with new light due to the pandemic affecting global supply chains, as studied by e.g., Badulescu et al. [
51]. Different supplier selection criteria might apply as political conflicts or other unpredicted events appear, that change the world market situation, highlighting the need for prioritization of sustainability and resilience.
2.3. A Value Constellation to Implement Digital Technologies
In manufacturing industries, the competition has shifted over the past decades from reducing costs to creating high-added-value, i.e., high customization, new business models and human capital, service dimension, and creating sustainable value [
52]. Manufacturing industries can have intrinsic and extrinsic motivations to use digital technologies in their production process to create values [
53,
54]. Digital technologies, often under the label I4.0, include, e.g., additive manufacturing, robotics and automation, big data, augmented reality, simulation, digital twins, IoT, cybersecurity, and cloud computing [
54]. From a value chain perspective, using digital technologies impacts the whole manufacturing supply chain, including the process of organizing design, production, sale, and delivery to the customer [
32]. The adoption of digital technologies can create the following values for the supply chain of manufacturing industries [
55]:
Improving financial performance,
Increasing resource efficiency,
Identification and traceability of raw materials,
Individualized or simulation-based technology products,
Improving overall equipment performance,
Increasing production flexibility, and
Creating new business models for interaction between customer and producer.
Many actors play a role in implementing digital technologies in the manufacturing industries’ supply chain, including TSPs delivering customer-oriented products and services based on digital technologies. TSPs are companies developing solutions to facilitate the implementation of digital technologies in various industries. The TSP and their collaborating companies can form a value constellation to co-create values by using digital technologies with the manufacturing supply chain [
55]. The value constellation [
20] represents a network of companies focusing on collaborating and receiving support from other companies or related individuals to co-create values and improve the competitive advantages of each other. Co-created value results from interactions among entities in a complex business system—a constellation—connecting knowledge and redesigning relationships [
20]. The proposed value involves technical, social, economic, and emotional resources that cannot be deployed individually [
56]. The illustration of the possible value constellation and created values presented in [
55] are shown in
Figure 1.
2.4. Sustainable Production through Digital Transformation
Sustainable production for a manufacturing industry corresponds to adopting strategies, actions, and activities that meet the current needs and necessities of the company while protecting, sustaining, and enhancing resources that will be needed in the future [
57]. The sustainable production output aims to use non-polluting, energy-efficient, economically viable, safe, and healthful processes and production systems for employees, communities, and consumers [
57,
58]. Sustainability goals can range from energy efficiencies and resilience to considering new forms of value related to products such as recycling and remanufacturing and product development in a resource-constrained world using a significantly lower amount of material and energy [
59].
Sustainable practices should extend to all phases of a product’s life cycle and to all stakeholders in the production value chain to achieve sustainability goals [
28]. To achieve these goals, the manufacturing companies may need to change production and consumption profiles, economic structure, production technologies, institutions, and organizational arrangements [
60]. Incremental improvements to existing technologies may not achieve these changes and often cannot happen without all stakeholders’ conscious, united, and focused efforts to strategically and systematically tackle the issue [
60]. A value constellation perspective on sustainability practices can consider the required collaboration among stakeholders to co-create some extent of sustainability goals and perform required changes together.
