A Project Management Model Based on Shared Understanding
- 2000

Ingår i: Proceedings of the 33rd Annual Hawaii International Conference on System Sciences, 2000. - : IEEE. - 0769504930

Konferensbidrag (refereegranskat)abstract
- Traditionally in industrial system development, the total project is decomposed into phases. The result from one phase, normally a document or a system component, is passed to the phase(s) to follow. The deliverables from the "phases" are often prescribed in standards or corporate guidelines. This metaphor, where understanding is packaged into documents, has been a cornerstone for our educational systems as well as for organizing engineering or social development projects. It is assumed that the understanding once achieved by the author(s) of the document will be transferred to its reader(s). In three longitudinal case studies of industrial development projects, a new view has evolved. The analysis team develops a capability to answer questions occurring on the fly, rather than writing down answers to initially stated issues. Our aim is to define a model based upon developing and making available shared understanding. The paper presents a survey of the case studies. In a fourth project an embryo of the new system development model is being applied and evaluated.

Organizational Knowledge as a Basis for the Management of Development Projects
- 2000
-
Konferensbidrag (refereegranskat)abstract
- This paper presents conclusions from longitudinal case studies on the industrial development of complex systems. The approach is to investigate whether the traditional document based development model can be replaced by on model built upon shared understanding in teams. The need for and use of supporting tools are also discussed

Stochastic optimization in system design
- 1981

Ingår i: IEEE Transactions on Circuits and Systems. - : IEEE. - 0098-4094 .- 1558-1276. ; 28:7, s. 702-715

Tidskriftsartikel (refereegranskat)abstract
- The nonlinear optimization problem and statistical design problem can both be formulated as a region search problem. In this paper, we present a stochastic optimization process, suitable for optimizing functions of a certain measure over generalized regions in R". Conditions for an optimal process are discussed, and examples of a wide range of different optimization problems are given. These include the optimization of constrained, discontinuous and random functions in both discrete and continuous variable space. Design centering and tolerancing of large size system subject to environmental disturbances are also treated.

Coordinating dependencies in global system development projects : the use of dependency diagrams
- 2004

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This work addresses the problems that arise in the coordination of complex system development projects. The empirical setting is based on studies at Ericsson and ABB, and the total project manager's instrument to manage and coordinate these projects. ABB used what they called dependency diagrams. Ericsson developed a method they call the anatomy concept. The approaches are used as a complement to the traditional work breakdown structure. The paper evaluates the ability of these notations to address the needs of the total project management. The studies have shown that it is crucial to create compact high-level pictures of the resulting product and its projects in order to make the dependencies obvious to everyone involved (organizations as well as persons). The paper stresses that when developing complex system solutions the traditional diagrams easily become complex and unreadable. Thus, there is a need for supplementing approaches.

Knowledge Integration – Balancing Between Anarchy and Despotism
- 2008
-
Konferensbidrag (refereegranskat)abstract
- A central issue in knowledge integration is how to achieve and maintain an optimal trade-off between differentiation and commonalization of knowledge. Too much emphasis on either side aggravates the efficiency of integration. The purpose of this paper is to make an inquiry into the trade-off problem from a particular theoretical perspective called the Activity Domain Theory. Two constructs from this theory are employed: the activity domain and the activity modalities. The activity domain frames the social fabric around actors working towards a common target, and the activity modalities are suggested as main dimensions through which humans coordinate their actions. We will utilize these constructs in analyzing a case study from ABB, a leading supplier of high-voltage equipment all over the world. Our conclusions are two-fold. First, complete commonality enforcement clashes inevitably with activity domain internal ideology. Second, management means such as images, need to be aligned with the activity modalities in order to achieve an optimal balance between anarchy, i.e., no commonality at all, and despotism, i.e., complete commonality. Based on these results, we suggest that the Activity Domain Theory may open up previously untrodden paths for theorizing about knowledge integration

Managing complex development projects : a case study of the use if the system anatomy
- 2005
-
Ingår i: Proceedings of Portland International Conference on Management of Engineering and Technology (PICMET), Portland, USA, 2005..
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper investigates the use of a construct called the system anatomy for planning and controlling projects developing complex systems. The anatomy shows, in a compact form, the most crucial dependencies in the system from the perspective of how it ‘comes-to-life’, hence the concept of an ‘anatomy’. The key point in using the anatomy for project planning is to develop and verify the system in the same order as it ‘comes-to-life’. The project plan in made up in three steps. The first step is to define the anatomy itself. This is followed by the group-ing of functions into verifiable integration steps called increments. Finally, regular time and resource plans are made for each increment. Thus, the planning can be characterized as an integration driven procedure. This ap-proach has been used extensively at Ericsson, a leading manufacturer of telecommunication systems world wide. It has proven to be very successful, especially in terms of promoting communication and developing a shared under-standing about the project.

Operationalizing coordination of mega-projects - a workpractice perspective
- 2006
-
Ingår i: Proceedings of IRNOP VII Project Research Conference. - BEIJING : PUBLISHING HOUSE ELECTRONICS INDUSTRY. ; , s. 574-587
-
Konferensbidrag (refereegranskat)abstract
- In this paper we propose a workpractice approach towards operationalizing the coordination of mega-projects. The approach matured over several years in development practice at Ericsson, a major supplier of telecommunication products and services worldwide. Key points in the approach are the management of critical dependencies and the construction of a communal understanding on how to coordinate projects. Coordination is seen as a workpractice, where actors provide coordination services to the project. We discuss some results from the application of the approach in relation to an ideal-type classification of mega-projects such as Weber, Rambo and Gaia. The main conclusion is that the suggested approach enables the coordination of extraordinarily complex megaprojects.
