Producing Task-Based Estimates of

This paper describes an approach to building an estimating tool which is based on a task-based model of effort, duration and cost. The potential benefit of such a tool - here called TABATHA - is that it operates at a more detailed level than existing tools, while the work required to plan a software project immediately becomes the input to the underlying estimating models. It will be argued that TABATHA is particularly useful on projects where user requirements change, because the effort involved in revising the project plan occurs at a task level, exactly the point at which TABATHA generates estimates

Projecting Projects: Choosing

this paper we analyse six years of experiences of teaching software engineeering using a client based approach. We develop guidelines to aid in the identification of clients and projects. This process needs to deliver both software engineering theory and provide a platform for later capstone projects. The paper describes each iteration of the course including content analysis of student reflective reviews. The paper concludes with ten point guideline
