On the alignment of the purposes and views of process models in project management / Tyson R. Browning in Journal of operations management, Vol. 28 N° 4 (Juillet 2010) 

Public ISBD [article]  in Journal of operations management > Vol. 28 N° 4 (Juillet 2010) . - pp. 316–332 Titre : On the alignment of the purposes and views of process models in project management Type de document : texte imprimé Auteurs : Tyson R. Browning, Auteur Année de publication : 2011 Article en page(s) : pp. 316–332 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Project  management  Process  modeling  Task-technology  fit  Decision  support Résumé : A project manager makes decisions based on what he or she sees and understands. In large, complex projects (or programs), a manager cannot see the entire “territory” between project start and completion and therefore must rely on models or “maps” to support planning and decisions. When it comes to planning and coordinating work, project managers commonly use a variety of process model views such as flowcharts, Gantt charts, responsibility assignment matrices, and narrative descriptions. However, these views may not contain the right information to best support the purpose or decision at hand. This paper investigates the fit between model views (a kind of technology) and the managerial decisions (a kind of task) they support. Through analysis of the literature and case study data, this research identifies: (1) a set of 28 purposes for which managers draw upon process models for decision support, (2) a set of 15 views of process models, and (3) a set of 56 information attributes involved in supporting the purposes and provided by the views. The paper develops new measures of the sufficiency and extraneousness of the attributes for each purpose and view. Analysis of the evidence suggests substantial misalignment between managers’ purposes and tools. Drawing on task-technology fit theory, the paper discusses the theoretical and managerial implications of these results and contributes a new construct, purpose-view alignment, which may help explain project success in future studies. The paper also presents insights for researchers and managers on how to develop customized views that are more suitable for particular managerial tasks.

Reconceptualizing the effects of lean on production costs with evidence from the F-22 program / Tyson R. Browning in Journal of operations management, Vol. 27 N° 1 (Janvier 2009) 

Public ISBD [article]  in Journal of operations management > Vol. 27 N° 1 (Janvier 2009) . - pp. 23–44 Titre : Reconceptualizing the effects of lean on production costs with evidence from the F-22 program Type de document : texte imprimé Auteurs : Tyson R. Browning, Auteur ; Ralph D. Heath, Auteur Année de publication : 2009 Article en page(s) : pp. 23–44 Note générale : Génie Industriel Langues : Anglais (eng) Mots-clés : Lean  production  Lean  manufacturing  Process  improvement  Agile  Aircraft  manufacturing  Learning  curves  Case/field  study Résumé : A central tenet in the theory of lean production is that the implementation of lean practices will reduce waste and thereby decrease costs. However, not all lean implementations have produced such results. Apparently, this effect is moderated by several factors, potentially even to the point of reversal. It is important to increase our understanding of how this might occur. In this paper, we explore how novelty, complexity, instability, and buffering affect the relationship between lean implementation and production costs. An interest in these factors drew us to study the case of Lockheed Martin's production system for the F-22, an extremely complex and innovative product. To build theory, we synthesize our empirical data from the case with other existing theory, such as theories of learning and complexity. Through this analysis, we develop a revised framework that reconceptualizes the effect of lean on production costs and use it to develop 11 propositions to direct further research. Included among these are propositions about how the timing, scale, and extent of lean implementation can regulate the benefits of lean. Furthermore, when the objective of lean is construed as the provision of value, we propose that this value is an emergent property of a complex process, different from the mere sum of the values provided by its constituent tasks. Therefore, the elimination of tasks will not guarantee cost reduction, and lean may provide even greater value by incorporating some aspects of agile manufacturing. Overall, we develop a fuller range of the effects of lean practices on production costs and illuminate how operations managers might control key variables to draw greater benefits from lean implementation.
