Abstract [en]

To proactively decide on the volume of capacity available in a period of time is referred to as capacity dimensioning. The actual dimensioning of capacity concerns both the regular capacity, to cater for systematic variations, and safety capacity, to handle the stochastic variations. Despite the critical impact of these two types of variations, the support in the literature is limited in terms of formal methods for resource management based on dimensioning of capacity in general, and of safety capacity in particular. Capacity is one aspect of resources’ capabilities and as a point of departure for developing such methods, the two overarching challenges of form-place-time matching and capacity balancing are defined. These challenges are exploited to provide a holistic approach to the combination of capacity and the generic form, place and time transformations performed to create customer value. This approach requires alignment between these types of transformation to enable a homogenous perspective on different types of resources such as machines and stock shelves. Such transformations are performed over time and a discrete-time period-based approach requires that the intra-period transfers and inter-period variations are integrated. Finally, the preconditions for proactive and reactive control related to capacity required are outlined. A foundation for capacity dimensioning is then established based on capacity balancing, period transfers and flow control.

Abstract [en]

To be competitive, it is important for companies to create a breeding ground for innovation without jeopardizing productivity. The challenge posed by industrial companies and the innovation research community is how to promote innovation while achieving efficient execution. The ability to balance execution and innovation is referred to as organizational ambidexterity (OA), which includes several dimensions, concepts and approaches where a central task can be identified. The purpose of this paper is to investigate what consequences result from different dimensions of a task in relation to the types of its actions, and their effects on OA. The focus of the task is firstly investigated, followed by the development of nine scenarios via combining the designers’ and the performers’ perspectives of the task. A brief analysis of the scenarios indicates that there is no single optimal scenario; rather, the scenarios represent different states that are appropriate for certain conditions, and dynamic adaptation should be encouraged in relation to the changing conditions. This type of dynamics is particularly expected to prevail in small and medium-sized enterprises (SME) because the roles that are responsible for tasks in these organizations are less specialized. Therefore, SMEs must define tasks that include both explorative and exploitative parts, either simultaneously or sequentially, to stimulate employees to work ambidextrously and thereby develop the concept of task-based ambidexterity.

Abstract [en]

Continuous flow is the guiding star for lean thinking and considered the ideal state for value streams. Despite this objective, it is seldom possible to obtain a state of continuous flow in a wider context. Decision makers face dynamic environments, and variable internal preconditions require a flow-thinking approach that provides support in response to these challenges. In the present study, the underlying logic of flow thinking is first identified as the key management layer, and thereafter the effectiveness of flow is targeted. The vision of continuous flow is challenged by different exogenous requirements that result in flow discontinuities. Flow thinking is then used to identify 10 decision categories based on these discontinuities, each related to a type of decoupling point and classified as time-based (exogenous) or conversion-based (endogenous). The flow-thinking approach is finally applied in three different contexts: a time-phased product structure, a modularized approach for planning and control, and a mixed-model value stream.

Abstract [en]

Customization in different flavors have been identified as an important differentiator if low-cost competitiveness is not viable. To provide a customer unique solution is however not the same as providing a solution that is designed and individualized for a particular delivery to a customer. These two cases are illustrations of how customer requirements may be fulfilled differently depending on the match between stated requirements and the solution offered. The range of solutions that can be offered is represented by a solution space consisting of either predefined or postdefined solutions. Predefined refers to solutions that are defined before commitment to a customer and postdefined refers to solutions that are defined after commitment to a customer. Both cases are constrained by a boundary of possible solutions but the postdefined solutions provide opportunities for bounded innovation beyond what the predefined solutions can provide. Combining the properties of the different solution spaces provides not only an operational definition of customization but also supports in identifying strategic opportunities for extending the solutions and types of customizations a business provides.

Abstract [en]

Balancing efficiency and responsiveness has been identified as an overall challenge for decision makers in supply chain management. The literature offers several strategies for managing this balance challenge. From a decision-making perspective this is a significant contribution but in combination the strategies also result in complexity related to the different alternatives offered. This study does, however, show that the strategies share a common foundation in terms of content related to decoupling thinking, which is based on flow discontinuities. Using the strategies’ individual strengths, a process is outlined that takes advantage of these strengths through a four-phase ongoing process.

Abstract [en]

Customization and customer-driven manufacturing are both explicitly based on the focal actor’s interaction with the customer actor. The impact of these aspects on the internal operations of the focal actor is relatively well known compared to the limited number of studies performed on the impact on the focal actor’s supplier. The purpose here is therefore to investigate how the concept of customization complements the concept of customer-driven and how customer requirements affect interaction between a supplier and the supplier’s supplier in a triad. Frameworks for different perspectives are developed where match and mismatch between the actors on the perception of flow driver and flow differentiation is highlighted. The frameworks are then applied on a case company to illustrate application.

Abstract [en]

Purpose

The integration of supply chains together with the disintegration of individual actors in the supply chain shifts the focus from actors to challenges in the interaction between actors. This paper sets out to identify risk strategies for different supplier interactions in triadic configurations, in order to outline supply strategies.

Design/methodology/approach

Companies participating in a research project recounted the challenges they faced regarding the integration of customer order-based management and supply from a triad perspective. Six triad configurations were identified, based on the literature, resulting in three risk strategies, which were empirically illustrated in practice by the participating companies.

Findings

A key finding is that a triad perspective for a customer-differentiated approach to supplier interaction results in a material classification that highlights the circumstances in which to apply ‘balance efficiency’, ‘postpone’, ‘balance responsiveness’ and ‘speculate’ supply strategies.

Research limitations/implications

The research has focused on process drivers and controllability and the results may require careful interpretation when there is a mix of standardized and customized products since further interaction differentiation then may be required.

Practical implications

The strategies developed herein provide guidelines for differentiated supplier interaction with explicit focus on triads where customer actors directly influence supplier actors. This approach highlights how outsourcing must be carefully executed when supplier actors are involved in delivery to customer orders.

Originality/value

The paper sheds new light on how customer requirements impact supplier interaction in terms of decoupling points related to both delivery strategy and control strategy. The study also presents a novel application of the Kraljic matrix in in terms of risk strategies in different triad configurations.

Abstract [en]

The notion of decoupling thinking has been well established in the manufacturing operations and supply chain management literature. This paper explores how this decoupling thinking can be applied in service operations and in particular in health care. It first reviews the relevant literature on decoupling fundamentals, the front- and back-office distinction, and new emerging decoupling thinking in service operations. Subsequently, a flow-based framework including content and process is developed for decoupling thinking in service operations. The framework provides an integrated perspective on customer contact, flow driver and flow differentiation (level of customisation). The framework hence, through flow differentiation, introduces the concept of standardisation versus customisation in a service context. This is followed by a health care case example to illustrate how the framework can be applied. The managerial implications are primarily in terms of a modularised approach to system design and management. The framework offers potential for benchmarking with other service systems as well as with manufacturing systems based on the shared foundation in decoupling thinking. Finally, suggestions are provided for further research opportunities derived from this research.

Abstract [en]

The human perspective and the flow perspective of businesses represent two areas of competence that study similar systems but with different frame of references. The human perspective involves ambidextrous learning that concerns how knowledge is developed and used for different purposes by individuals or groups of individuals. The development of knowledge for new situations is referred to as ‘exploration’, while ‘exploitation’ refers to execution in known and stable contexts. Furthermore, decoupling thinking is important from a flow perspective and concerns how a value-delivery package is created. This type of thinking decouples the flow perspective into segments with different characteristics that are significant for process management. The examples presented in this paper are distinctive drivers of flow in terms of speculation or commitment, and the level of customisation. By combining these two perspectives, a set of 15 scenarios is identified for further research on ambidextrous learning in a decoupling thinking context.
