- Information is a critical factor to support a proactive behaviour of operators in complex work settings characterized by flexible levels of automation and need for knowledge-based decision making. In this conceptual paper the authors define proactive behaviour as the ability of operators to control a situation by taking action in advance. Information requirements that enable proactivity and different control behaviour are identified. Moreover, several demands on the information support system are outlined. Further, the paper presents some implications for management as a result of the new work role of the operator regarding decision making, planning, and control.

Considering design demands of a proactive assembly system : A position paper
- 2007
-
Ingår i: Proceedings of the 1st Swedish Production Symposium.
-
Konferensbidrag (refereegranskat)abstract
- The paper reviews the idea of proactivity in an assembly system with respect to information and decision making. It begins with an explanation about the term proactivity and moves on to a discussion of necessary changes of the assembly system to become proactive. Further, this paper will consider the role of information in a proactive assembly system and its impact on the proactive behavior of an operator. The method applied in this paper is a literature study.

Exploring requirement specification of the production system – a position paper
- 2009

Ingår i: Paper presented at the 3rd SwedishProduction Symposium. - Gothenburg.

Konferensbidrag (refereegranskat)abstract
- In today’s turbulent environment, manufacturing companies are forced to efficiently change or develop production systems that are robust and dynamic enough to handle changing production situations during its entire life-cycle. To achieve such a production system requires a structured development process that should be carried out simultaneously to the product development process and considers the company’s product portfolio. Within a structured development process, the requirements specification of the proposed system is vital since it will guide the design process and the evaluation of the system on a conceptual as well as a detailed level. The aim of this paper is to address the requirement specification process that covers all aspects of the production system to be designed. This paper argues for the need of a holistic view in the requirement specification process of production systems. A holistic view of the overall process will facilitate to manage the various demands and categories important to deal with in the specification of requirements. Based on the holistic view it will be possible to identify the gates and stakeholders of the process itself, but also the substantial content of this process map.

Information Requirements in a Proactive Assembly Work Setting
- 2009

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Due to the increasingly competitive climate, the on-the-job behaviour of an operator becomes more and more essential for the success of a manufacturing company. In working contexts, which are dominated by changes and uncertainty, knowledge-based behaviour and work role aspects that cannot be formalized, proactive behaviour of the operator can contribute to competitive advantages. Without waiting to be asked or instructed, the proactive operator uses his/her own initiative to change the present situation in the light of anticipated future demands and needs. In order to obtain and support proactive behaviour among operators on the shop floor, access to correct and essential information at the right time and in the right way is one important requirement. Hence, the objective of this thesis is to analyse information requirements in order to provide a basis for information interface design that supports a proactive behaviour of assembly operators. A system approach was adopted and the foundation for this thesis is an extensive literature review. Further, an empirical case study was performed at a Swedish manufacturing company. The case study was analysed using work domain analysis and the purpose of this case study was to investigate the information used in an assembly work setting to accomplish various activities related to proactive behaviour. The result of this thesis is a synthesis of the information requirements found in the literature study and the empirical findings. The thesis argues that the ability of the assembly operator to anticipate and plan for changes is highly dependent on what information to provide and when to present this information to the assembly operator. Both operational information and information related to the development of the assembly work setting are required to enable proactive behaviour of the assembly operator. When analysing the empirical findings in relation to the information requirements stated in literature, it was found that proactive behaviour of operators is, above all, related to access to why and what information. How-related information, however, can also be relevant for the proactive assembly operator if it relates to knowledge-based behaviour. Additionally, the expertise of the assembly operator refers to the control behaviour performed by the operator and determines the amount of information needed by the assembly operator. Finally, for information to be experienced as useful by the operator, it has to fulfil various criteria determining information quality. The thesis concludes that by analysing the type and amount of information to be presented to the assembly operator, and how to orchestrate information in a systematic way, it is possible to change the assembly operator from a passive monitor to an active problem solver.

Konferensbidrag (refereegranskat)abstract
- Proactive behaviour of an assembly operator can be essential in a complex and uncertain work context, where it is not longer possible to anticipate and predefine all possible work situations an operator has to handle. Access to correct and essential information is a critical means to support proactive behaviour. This paper clarifies information requirements of a proactive assembly work setting by analysing the information needed of an assembly operator to anticipate and prepare the work system for external and internal changes. The results show that proactive behaviour is above all related to the access to information answering why and what-questions. Additionally, the expertise of the assembly operator refers to the control behaviour performed by the operator and determines the amount of information needed by the assembly operator. Finally, for information to be experienced as useful by the operator, it has to fulfil various criteria determining information quality.

Towards a Methodology for the Assessment of Information Requirements in a Proactive Assembly Work Setting
- 2008

Ingår i: Swedish Production Symposium, November 18-20, 2008. ; , s. 311-318

Konferensbidrag (refereegranskat)abstract
- Assembly work settings enabling proactive behaviour of the assembly operators are considered to be an important factor enabling customization of assembly work. As a consequence, access to necessary and essential information is a critical means to support proactive behaviour of assembly operators. In this paper we propose a methodology for assessing information requirements supporting operators’ proactive activities and decisions. The methodology is based on work domain analysis and it was used for assessing the information flow in a real assembly setting. By analysing the structure of information exchange and the hierarchical means-ends relationships a number of conclusions could be drawn. The first is that in order to consider information needed for all possible work activities, work domain analysis is a suitable approach. Additionally, proactive behaviour is related to the access to information answering why and what-questions. Furthermore, development towards more proactivity among assembly operators may necessitate decentralised decision-making. It is also concluded that in order to identify intentional constraints of an assembly system with increased proactivity, it is necessary to examine the levels of automation. Furthermore, to reach productivity gains the levels of competence must be developed so that most proactive decisions will remain on the skill- or rule-based levels.
