“…Many SPs communicate end-of-life support to their customer organizations several years in advance with an expectation that organizations would use the time to migrate to newer solutions. However, if the top management feels that such needs are unnecessary, they may not make the announcements in a timely manner, which in a way points to poor TMC, which not only leads to poor decision-making and/or inadequate budget provisioning, but also contributes to SF and thereby hinders the process of SR (Alelyani et al , 2019). Sometimes, SPs intentionally obsolete existing technology to tempt the customers to purchase newer versions or technologies while at the same time gradually withdrawing support for older technology, thus, intentionally making effective recovery difficult.…”

“…Quite often, the intended life of such an implementation is greater than the actual life of the software or its hardware components, necessitating upgrading of COTS elements within the system. Failure to do so may lead to system availability issues or even an SF (Alelyani et al , 2019). As seen from the example, the suppliers of COTS elements upgrade their hardware/software, which then accelerates the pace of technology obsolescence. Life cycles match (longer lifespan of products and parts, both): This demonstrates a life cycle match where both products and its components have longer lifespans.…”

Purpose To address service failure issues, scholars have recognized several service recovery (SR) mechanisms. However, there exist many barriers that retard an effective SR process, and those often lead to negative consequences. Although this is a generic problem applicable across markets, it becomes critical in B2B markets, as they deal with high impact and corporate customers. The purpose of this paper is to identify these SR barriers in B2B markets and explore their linkages toward identifying the key driving barriers. Design/methodology/approach A four-phased methodology to address this call in the IT services industry was used. First, the identification phase led to the selection of 27 barriers based on literature. Second, in the prioritization phase, 12 salient barriers were prioritized with the help of an expert panel. Third, in the modelling phase, the total interpretive structural modelling (TISM) technique was used to examine the mutual influences among these barriers toward modelling their linkages using a digraph. Finally, in the classification phase, these barriers were graphically plotted and classified into four quadrants based on their dependence and driving powers by using Matriced Impacts Croisés Multiplication Appliquée á un Classement (MICMAC) analysis. Findings Two strategic barriers, namely, technology obsolescence and poor top management commitment, presented the strongest challenges against effective SR, as they were least dependent on other barriers and exerted strong influence over the operational barriers to executing SR. Practical implications Because the strategic level barriers, exerting strong influence against effective SR, arise from the strategic choices of board and the C-suite, this paper helps them anticipate the recovery-related after effects of their choices, thus helping them in making better decisions. Originality/value This paper contributes to research as it is first of its kind to explore and link SR barriers in B2B markets.

Kongsberg Maritime (KM) experiences growth in the number of reactive obsolescence events. Time constraints in the decision‐making process limit options on how to resolve obsolescence. The total cost trajectory of labor and money consumed to resolve obsolescence is not sustainable for KM going forward. Last time buy (LTB) is one of many tools in obsolescence management. LTB is attractive because it does not require reengineering, requalification, or redesign. Despite its benefits, LTB should only be used if the total cost of LTB outweighs other alternatives. In this study a model was created to predict component obsolescence and quantifying the total cost of LTB. The research assumes obsolescence management less effective when dominated by LTBs. By proactively using this model, decision‐makers can evaluate alternatives compared to LTB selecting the most cost‐effective solution. Feedback from decision‐makers confirms a need to have, and willingness to use, the model.

“…14 Reviews of obsolescence management for such industrial and cyberphysical systems have identified that "there are no studies which focus on existing obsolescence management strategies specifically for COTSbased CPS systems." 15 These reviews highlight the importance of a systems perspective in enabling obsolescence management to reduce performance risk and maintain systems reliability, availability, maintainability, and cost-control, with importance across all system life cycle phases. 15 The goal of this work is therefore to address the challenge of obsolescence planning for industrial cyber-physical systems using a generalized approach congruent with these needs.…”

Risk‐based approach for managing obsolescence for automation systems in heavy industries

Obsolescence is an important consideration in the management and engineering of heavy industrial facilities. Examples of these could include refineries, chemical plants, and other large‐scale materials processing facilities. These facilities have lifetimes of many decades but operate on software, automation hardware, and other electrical equipment that reaches obsolescence much sooner than the rotating equipment, unit operations, and other major systems of the facility. This work proposes a method to manage obsolescence of automation and electrical systems at industrial sites. This risk management method was developed by first analyzing a database of upgrade projects at several industrial sites and identifying parts that had been replaced due to obsolescence. The analysis was used to prioritize replacement of obsolescent parts based on the average operational lifespans, their criticality in operations, their manufacturer's continued production state, and other factors. Based on those results, a taxonomy of obsolescence risk, and a risk assessment plan were developed to manage the replacement of parts. The value of this proposed management strategy was validated through its application to 13 heavy industrial facilities. The results indicate a reduction of roughly 70% in reactive replacements due to obsolescence after the major upgrade and a 24% reduction in unplanned downtime due to part failure during normal operations. While this study is focused on heavy industries, the proposed method for identifying and managing component obsolescence can be applied to other industries and systems.
