Abstract
Purpose
Recent studies have argued that companies may actively implement practices to mitigate disruptions in their supply chain and reduce the extent of damage on performance. Other studies have shown that disruptions may propagate in supply chains, leading to consequences that are more negative and raising doubts on the effectiveness of mitigation strategies implemented downstream. This study investigates the influence of supply chain complexity on the two phenomena and their interplay, taking a focal company's perspective.
Design/methodology/approach
A systematic procedure for data collection, encoding and aggregation based on incident data mainly from secondary sources was used. Multiple regression models were run to analyse direct and moderation effects involving resilience, distance of impact location from trigger point, and supply chain complexity on weighted performance change.
Findings
Supply chain complexity is found to have positive moderation on the ripple effect of disruption. Resilience capability remains to have dominating direct positive effect in mitigating disruptions when supply chain complexity is taken into account.
Research limitations/implications
This study extends the research discourse on supply chain resilience and disruption management with focus on the supply side. It demonstrates that, along with the severity of the disruption scenario, the ripple effect must also be considered when analyzing the benefits of resilience practices implemented by the focal company.
Practical implications
Complexity in the supply chain can only help to smooth-out the rippling effects of a disruption, which go largely beyond supply-demand unbalances and lead time fluctuations. To mitigate it better, the focal company has to act proactively with adequate resilience practices, which also connects to the importance of better visibility across multiple supply chain tiers.
Originality/value
To the best of the authors' knowledge, this is the first study that empirically tests the benefits of resilience practices and the ripple effect of disruptions under the moderation role of supply chain complexity.

Abstract
Purpose
Many studies have found that Lean practices provide better performance in a stable business environment. However, there is limited information on how Lean practices influence performance gains (defined in this paper as improvement and sustenance of performance) in an uncertain (complex and dynamic) environment. This study aims to investigate how the implementation of Lean helps to sustain performance in such context.
Design/methodology/approach
The study draws on an in-depth investigation of two capital goods manufacturing engineer-to-order (ETO) cases, in which performance sustenance is discussed in relation to the extent, locus and extensiveness of implemented Lean practice bundles.
Findings
Findings indicate that a higher extent of Lean practices’ implementation, covering both shop floor and transactional processes, increases the possibility of performance sustenance in ETO. Furthermore, a coherent approach in the pre-, during- and post-implementation phases of the Lean change process is required to foster performance sustenance. Lean practices in ETO are modified to suit context change from repetitive manufacturing.
Research limitations/implications
This study proposes performance sustenance as a performance measure in a highly uncertain context, such as ETO, as a single reference cannot effectively measure performance improvements over diverse orders. From this perspective, appropriate Lean implementation contributes towards building capabilities for flexibly and proactively managing uncertain circumstances.
Practical implication
Even companies operating in highly uncertain (complex and dynamic) contexts may benefit from significant performance gains, thanks to the Lean implementation. This can be achieved by a balanced implementation of practices at shop floor and transactional processes, and their mindful customisations.
Originality/value
The study compares Lean implementation in ETO with that of high-volume–low-variety systems established in the literature. It qualitatively discusses how Lean implementation as an overarching effort both in shop floor and transactional processes leads to better sustenance of achieved performance improvements in shop floor under high uncertainty.

Abstract
Purpose
This study aims to investigate the influence of supply chain (SC) complexity on the effectiveness of resilience capabilities in mitigating SC disruptions. Hypotheses about direct and moderating influences of complexity on resilience capabilities and performance change after disruption are built and quantitatively tested.
Design/methodology/approach
Partial least square-based structural equation modelling with formative constructs was used as an overall approach. Secondary data on SC disruptions, related performance change and resilience practices were collected from multiple sources through a predefined procedure. The collected data were systematically encoded prior to performing statistical analysis.
Findings
SC structural complexity is found to have a significant positive relation with performance improvement after disruption, along with resilience capability; it also positively moderates the resilience–performance link.
Research limitations/implications
The SC complexity factors the authors considered in this study do not include dynamic forms because of the nature of data collected. Future research may attempt to include and test whether the results of this study also hold when additional complexity parameters are taken into account.
Practical implications
Managers are often trying to reduce SC complexity. This study implies that some level of complexity is beneficial also for a better recovery of operational performance affected because of disruption. Resilience capabilities become more effective when leveraged on complexity in the SC.
Originality/value
This is the first study to empirically investigate the influence of SC complexity on the resilience–performance link.

Abstract
Purpose
This study explores how industrial production companies adjust implementation strategies to deliver value with their company-specific production system (XPS) in a multi-site setting. Implementing an XPS is part of operations management and is supposed to mobilise employees resource-efficiently to increase operational performance.
Design/methodology/approach
Based on a multiple-case study, this study qualitatively explores the patterns of implementation decisions within and between five multi-site production companies. Conclusions were drawn on a mix of timely and retrospective data gathered through individual interviews with senior managers and joint workshops where they interacted and shared experiences.
Findings
This study identifies the fact that companies respond differently to non-unique implementation challenges, constituting various decision patterns when implementing their XPS. This paper identifies four implementation strategies (Education, Tool, Pragmatic and Culture Strategy) that explain various implementation setups. More experienced companies frequently shifted between strategies to return to previously de-prioritised implementation aspects.
Originality/value
This paper offers a dynamic model for XPS implementation in contrast to a simplified tool–system–culture sequence in literature today. Companies that deliberately shift implementation strategy by understanding the benefits and challenges of their decisions are more likely to keep momentum in the XPS implementation.

Abstract
Purpose
The unpredictable failure of submersible pump (SP) in groundwater irrigation systems has considerable negative economic consequences. The purpose of this paper is to develop a total cost minimization model that aims to optimize maintenance actions for SP. It reports on simulation-based stochastic scenario analysis for evaluating total cost of maintenance.
Design/methodology/approach
Stochastic simulation modeling has been performed for failure of pump motor and corresponding maintenance. Five alternative scenarios were compared for total cost over 15 years starting with empirical data from a northern Ethiopian site. Downtime probabilities and spare part supply uncertainty have been considered in the mathematical model. The model is also validated using multiple ways.
Findings
The scenario comparisons indicate that despite the challenges of accessing SP doing one motor rewinding for each purchased pump system upon failure (preferably with shorter supply lead time and variability) seems to result in lowest overall costs for the time horizon considered.
Practical implications
The model should help to make informed practical decision regarding planning and management of SP failure systems in a developing economy context. This should, therefore, lead to better revenue for smallholder farmers and improved food security in similar context.
Originality/value
There are limited number of publications that consider the life cycle costs with stochastic analysis when it comes to maintenance of SPs. To the best of the authors’ knowledge, no paper has previously directly addressed maintenance cost optimization for SP in irrigation. The study could be used to develop more sophisticated stochastic models with more efficient algorithms and consideration of additional sources of stochasticity for such system.

Abstract
Purpose
The purpose of this paper is to investigate synergy/trade-off relationship between lean and operational resilience paradigms upon disruption. Lean and resilience are operationalised with practice bundles and core functions, respectively.
Design/methodology/approach
The study uses the Bayesian inference approach to analyse systematically encoded data from firms that faced disruptions in their supply chain. The data were collected from publicly available sources, and encoded using predefined constructs prior to analysis.
Findings
Findings show that the synergetic relations between operational resilience and lean in mitigating performance losses outweigh the trade-off. Just-in-time/flow and total productive maintenance lean practices appear to be major sources for the trade-off; there is limited-synergy leveraged on the anticipative (sense) capability of operational resilience.
Research limitations/implications
The dependence on secondary data and small sample size are possible limitations. Future research may employ large-scale studies with the same encoding approach by combining both primary and secondary sources.
Practical implications
This study implies that companies need not abandon their lean implementation in order to be resilient against unanticipated disruptive circumstances. Most lean practices can be used to leverage agility to mitigate disruptions.
Originality/value
This is a first study to empirically compare synergy/trade-off between operational resilience and lean with reference to changes in operations performance upon disruption. It is also a first study to investigate sources of synergy/trade-off at lean practice bundles and resilience core functions level. This is a much more practical level compared to how previous studies have addressed the issue.

Abstract
Purpose
The purpose of this paper is to conceptualize a typology of supply-side resilience capabilities and empirically validates these capabilities and their constituent bundles of practices.
Design/methodology/approach
The study is primarily qualitative, employing the critical incident technique to collect data across 22 firms and seeking to validate how and why practice bundles form and relate to operations performance. It contains a frequency of occurrence analysis for the purpose of triangulation, a minor statistical part to provide some additional evidence of bundle formation and correlation between adoption of bundles of practices and recovered operations performance after upstream supply chain disruptions.
Findings
Four supply-side resilience capabilities are conceptualized along two dichotomous dimensions – “proactive/reactive” and “internal/external” – in a 2×2 matrix as proactive-internal, proactive-external, reactive-internal and reactive-external resilience capabilities. Empirical support for the conceptualized typology is found. Bundles of specific practices that can be associated with each capability are identified. Moreover, the study finds a relationship between these practice bundles and recovered operations performance.
Research limitations/implications
The statistical part is used just to provide some additional evidence through factor and regression analyses that these capabilities exist and do benefit adopting firms.
Practical implications
Specifies practices that lead to recovered operations performance in the event of supply disruptions.
Originality/value
Advances current theory by operationalizing resilience as a set of dynamic capabilities in terms of practice bundles that aid in recovering operations performance upon supply disruptions.

This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context.
Findings
As soon as the UK voted to leave the European Union (EU) in 2017, one of the key discussions among businesses throughout Europe centered on what the likely impact would be on supply chains involving UK companies. Whether you were a mainland European country with supply chain partners in the UK, or a UK manufacturer that depended on European companies for supplies, the uncertainty and potential disruption to well-grooved supply chain processes became a major headache. At first, it was the uncertainty that proved the major issue as governments played politics and refused to define the likely deal that would enable supply chain terms to be put in place. As the UK left the EU and the terms of the overall deal became clearer, firms then had to work out how whether any necessary changes to their supply chains were required.
Practical implications
Provides strategic insights and practical thinking that have influenced some of the world’s leading organizations.
