Sales and operations execution: An explorative study on potential effects

NOFOMA , 2020

Purpose Sales and operations planning have a long history in practice and has been researched ext... more Purpose Sales and operations planning have a long history in practice and has been researched extensively. It has been proposed that this tactical concept needs to be aligned with a more operational, short-term concept, hence the purpose of this paper is to investigate how sales and operations execution (S&OE) can enhance the performance of a supply chain by analyzing contingency factors regarding design and use. Methodology A multiple-case study approach investigates the potential outcome of implementing a S&OE process in various contexts. Empirical data from several firms in various industries are analyzed according to common and unique factors affecting the potential result. Findings This study identifies critical design for an S&OE process to have a positive outcome in different contexts. Furthermore, relevant data is identified, as well as actors essential for successful usage. Finally, we present, by using knowledge management theory, the importance of integrating S&OE in the planning hierarchy and how the S&OE practice leads to results. Research implications This study details the understanding of how sales and operations execution affects the supply chain performance, given different contextual aspects. Practical implications This study shows the potential impact of implementing S&OE for different types of businesses, as well as giving guiding principles for its design. Original/value S&OE as a concept is today merely described as white papers and consultancy reports. To our best knowledge, this is the first academic study that explores the sales and execution phenomenon in a real-world context. Keywords: Sales and operations execution, Sales and operations planning, Supply chain execution, Case study, Contingency theory, Knowledge management theory.

Exploring factors causing and amplifying ‎delivery schedule instability: An OEM ‎perspective from the ‎automotive industry

NOFOMA , 2020

Purpose The purpose is to explore how OEMs generate instabilities in material delivery schedules ... more Purpose The purpose is to explore how OEMs generate instabilities in material delivery schedules ‎within automotive supply chains. ‎ Design A multiple case study of three automotive OEMs were conducted to collect qualitative and ‎quantitative data as to explore factors causing and amplifying schedule instability measured ‎by inaccuracy and nervousness. The quantitative data includes two-year delivery schedule ‎history, and the qualitative data includes the OEMs’ manufacturing planning and control ‎processes and policies.‎ Findings From literature and cross-case analysis, the study generates a framework of causing and ‎amplifying variables. Four factors (take rate, transport lead times, unit loads, and pick-up ‎frequency) were proposed to have common and significant impact on schedule instability. ‎Take-rate and transport lead time amplify schedule inaccuracies, and pick-up frequency ‎amplifies schedule inaccuracy for items with low take-rates.‎ Research implications The quantitative study analyses the amplifying effect of a few selected factors at one of ‎the OEMs. Future studies may address additional factors including causes like production ‎disturbances and may validate the findings at more OEMs.‎ Practical implications Understanding the amplifying effect at an item level guides the instability dampening ‎policy making at OEMs to, for instance, establish clusters of components with sensitivity ‎profiles‎.‎ Original The study compliments previous frameworks with refined and additional factors, exploring ‎empirically rich data about how OEMs, an understudied perspective, propagate schedule ‎instability, an area dominated by simulation studies.‎ Keywords: Schedule Instability, Nervousness, Schedule Inaccuracy, MRP, Rescheduling.‎

A tactical demand-supply planning framework to manage complexity in engineer-to-order environments: insights from an in-depth case study

Production Planning & Control, 2020

This study expands the understanding of managing complexity to obtain demand-supply balancing, focussing on the tactical planning logic of the order fulfilment process. An in-depth single case study was conducted and data describing the order fulfilment process at a construction company were collected and analysed. Findings suggest a tactical-level planning process framework, incorporating nine key decisions and three crucial activities, and their potential complexity-reducing and complexity-absorbing impact. The study contributes to the theoretical discussion of complexity in management practices, linking demand-supply balancing as a performance measure. The findings guide practitioners in ETO settings on anticipating potential medium-term consequences of key decisions on capacity. This emphasises the need of proper IT support to apply knowledge generated from previous projects and conduct comprehensive and robust scenario-based analyses.

Managing the dynamic needs of engineering resources through sales and operations planning

The areas of uncertainty and how they are addressed by S&OP are investigated in an engineer-to-order setting. Uncertainties stem from customer orders and critical competences and are minimized through integrating engineering resource planning into S&OP sub-processes and organization, and through explicating methodologies using IT tools that also support scenario planning. To improve the effect of S&OP, measuring short- and long-term performance is recommended, and aligning S&OP with the bidding and organization development processes is important. Future research may replicate this study using multiple cases.

Exploring contextual variables of tactical planning within the construction industry

The preliminary result using a Delphi study including architects, clients, contractors, researchers, and suppliers indicates that the top five most important context dependencies are: Several kinds of stakeholders, Several planning phases, Lack of standardisation in planning, Low information sharing, and Opportunistic behaviour. Based on the patterns between the different expert groups two propositions are developed, indicating lack of shared understanding of planning between different stakeholders in construction and a project focus when thinking of planning.

Towards a balanced supply and demand within construction contracting

Based on literature and a case study from the construction industry, three main decisions within the bid preparation process are found to have mid-term impacts on supply-demand balancing and business alignment. The bid/no-bid decision regulates demand by validating and prioritizing projects, and capturing valid project specifications. The decisions of team formation and construction methods regulate supply by identifying mid-term resource needs, optimizing resource utilization, and establishing delivery plans.
