Flexibility is one enabler of efficient use of resources and is therefore an antecedent to sustainability. The purpose of this article is to identify supplier flexibility variables in, and related to, the order-to-delivery (OTD) process and categorize them into a framework, followed by empirically exploring the framework.Design/methodology/approachA perception-based survey was sent to Swedish purchasing managers. 289 responses were received. After descriptive gap analysis, exploratory factor analysis was applied to structure the responses into factors. This formed the basis for hierarchical linear regression analysis, explaining supplier flexibility.FindingsA conceptual framework, specifying supplier flexibility into volume, delivery and information exchange dimensions and relating these dimensions to the OTD process, was developed. Significant negative gaps between actual and demanded volume flexibility and delivery flexibility were identified, while positive gaps were found for information exchange flexibility. The factor analysis revealed three factors. The regression analysis verified that OTD-related information exchange flexibility and OTD-related volume and delivery flexibility explain the variation in OTD-specific flexibility and are important antecedents for supplier flexibility in the OTD process.Research limitations/implicationsA contribution to research is the framework – with defined, related and empirically validated flexibility types.Practical implicationsThe study proposes a perception-based way to capture supplier flexibility in the OTD process, which is of practical relevance when evaluating suppliers.Originality/valueIdentifying, conceptualizing and capturing types of supplier flexibility in the OTD process is new related to academic literature. Also the wide empirical study mapping supplier flexibility gaps is unique in its focus.

The purpose of this study is to measure the gaps between the engagements of shippers (i.e. logistics buyers) and logistics service providers (LSPs) in different green logistics practices (GLPs) throughout the key phases of the logistics purchasing process: request for proposal, negotiations, contracting and execution.Design/methodology/approachA large-scale survey of shippers and LSPs in Sweden was conducted. Respondents were 331 firms (169 shippers, 162 LSPs). Mean values of the actors' perceptions were analysed using independent- and paired sample t-tests.FindingsWhile this study supports previous research indicating that LSPs engage more extensively in selling GLPs than shippers do in buying them, it shows that this conclusion does not uniformly apply to all GLPs nor all purchasing phases. Three patterns emerged for the gaps between the actors' buying-selling engagements throughout the purchasing process: (1) steady and wide gaps, (2) steady and narrow gaps and (3) emergent gaps. Distinct GLPs were associated with each pattern. It is also shown that the prioritisation of GLPs is fairly aligned between shippers and LSPs.Research limitations/implicationsThis study contributes to the green logistics purchasing literature by systematically and simultaneously creating three types of distinction, between (1) shippers and LSPs, (2) different GLPs and (3) different logistics purchasing phases. Future studies could replicate the analysis in countries other than Sweden.Practical implicationsManagers of shipper/LSP firms learn tips to spot the GLPs that their partners prioritise, enabling them to modify their purchasing/marketing strategies accordingly.Originality/valueThe three types of distinction represent a novel approach in the green logistics purchasing literature.

Recent studies have highlighted the importance of adopting a contingency approach to configuring omnichannel warehouses. Nonetheless, research on how various contextual factors influence the selection of warehouse configuration is scarce. This study fills this knowledge gap by exploring how and why certain configurations fit in different omnichannel contexts.Design/methodology/approachA case study is conducted with six leading Swedish omnichannel retailers. Focusing on outbound warehouse configurations, data are collected through interviews, on-site observations, and secondary sources. A multistep analysis is made, including both pattern matching and explanation building.FindingsThe qualitative analysis reveals 16 contextual factors, of which assortment range, requested online order fulfillment times, goods size and total transactions are the most influential. The study shows how contextual factors create different challenges, thereby influencing the choice of the configurations. In addition to market dynamics and task complexity, the study describes four categories of the factors and related challenges that are particularly important in omnichannels: speed, space, economies of scale and tied-up capital.Research limitations/implicationsThe findings highlight the importance of understanding context and imply that multiple challenges may require trade-offs when selecting configurations, for example, regarding what storage, processes and resources to integrate or separate. To confirm, extend, challenge and further operationalize the ideas and observations put forward in this paper, an agenda with future research issues is given for this accelerating, contemporary phenomenon.Practical implicationsManagers could leverage the frameworks proposed for the contextual profiling of their current and future positions. The frameworks provide support for understanding the important challenges and potential trade-offs and developing aligned configurations.Originality/valueThis study is original in the way it provides in-depth, case study findings about contextual factors and their influence on omnichannel warehouse configuration.

Service modularity promotes efficiency at the provider end of the supply chain and customisation at the customer end. The purpose of this paper is to investigate how logistics service modularity contributes to sustainable development through the means of energy efficiency. This is analysed in the context of logistics services for household waste collection.Design/methodology/approachA single case study methodology with embedded units is adopted where semi-structured interviews were conducted with a waste service provider (WSP) and buyers (municipalities) in Sweden, focussing on five types of logistics services for waste collection: collection of food and residual waste at apartments and one-family houses, as well as collection of gardening waste. Service modules are identified and analysed by blueprinting the service.FindingsThe findings show different service modules – standardised or customised – and their contribution to sustainable development operationalised through energy efficiency. Principles for an energy-centric service design are proposed.Research limitations/implicationsThe research is limited to Swedish household waste collection setting. Promising efficiency through standardisation, logistics service modularity has a potential to improve energy efficiency as well. This neglected link between sustainability and service modularity offers fruitful research avenues.Practical implicationsThis research is of practical relevance to waste logistics service providers and the municipality by suggesting principles for energy-centric service design. The service blueprint enables using logistics service modularity for improving energy efficiency in different logistics service settings.Originality/valueThis research incorporates an environmentally sustainable development perspective into logistics service modularity and contributes to the literature by exploring how energy efficiency is improved by modular design of logistics services. Furthermore, the study is one of the first to use service blueprinting to analyse logistics service modularity, providing a methodological contribution to that field in general and logistics in particular.
