This paper analyzes the problem of optimal job design when there is only one contractible and imperfect performance measure for all tasks whose contribution to firm value is non-verifiable. I find that task splitting is optimal when relational contracts based on firm value are not feasible. By contrast, if an agent who performs a given set of tasks receives an implicit bonus, the principal alwa...

In this paper we critically review task analysis models and techniques. These approaches to task analysis are discussed in order to develop a richer picture of human activity, while analyzing their limitations, general weaknesses, and possibilities for improvement. We consider their ability to determine the appropriate set of atomic actions in a task, their effect on workers’ motivational needs...

This paper discusses an iterative, engineering approach with an improved Conceptual Design Stage for the design of better hypertext. We emphasize the importance of getting design right “up front” so that many design blunders can be avoided. Task analysis and cognitive user modelling techniques are used to make design recommendations for rapid prototyping and testing of a prototype hypertext. We...

Many task analysis techniques and methods have been developed over the past decades, but identifying and decomposing a user’s task into small task components remains a difficult, impractically time-consuming, and expensive process that involves extensive manual effort (Sheridan, 1997; Liu, 1997; Gramopadhye and Thaker, 1999; Annett and Stanton, 2000; Bridger, 2003; Stammers and Shephard, 2005; ...

A contemporary approach to describing and theorizing about joint human endeavor is to posit ‘knowledge in common’ as a basis for awareness and coordination. Recent analysis has identified weaknesses in this approach even as it is typically employed in relatively simple task contexts. We suggest that in realistically complex circumstances, people share activities and not merely concepts. We desc...

Since the 19th century, studies of mathematics at university have been a main component usual preparation for teaching secondary level. Already around 1900, Klein pointed out that specific measures are needed to ensure mathematical becomes useful teacher, and he insisted universities themselves must take responsibility these measures. In this paper, we discuss problem, as it presents itself in ...
