Controls in Flexible Software Development
Control and flexibility may appear an unlikely pair. However, we propose that effective flexible software development processes must still provide clear control mechanisms to manage the progress and quality of the resulting software products. This paper presents a conceptual study to understand the types of control found in flexible software development processes, termed controlled-flexible approaches. Control theory is used as a lens to study the control mechanisms found in plan-driven and flexible processes. We extend current thinking to include emergent outcome controls and clan controls for team coordination in our taxonomy of control mechanisms. Several popular flexible processes are analyzed for control mechanisms. We conclude with a brief discussion of future research directions
Possible versus desirable in instructional systems: Who's driving?
This paper takes a pragmatic stance that the key to successful application of technology in education is good teaching: using technology only when it is a cost‐effective servant of pedagogy. The paper discusses some fundamental issues in the production of computer‐based materials, and considers them in the context of an on‐going evaluation of an Internet courseware project

A computer-based product classification and component detection for demanufacturing processes
This is an Author's Accepted Manuscript of an article published in International Journal of Computer Integrated
Manufacturing, 24(10), 900-914, 2011 [copyright Taylor & Francis], available online at:
http://www.tandfonline.com/10.1080/0951192X.2011.579169.The aim of this paper is to propose a novel computer-based product classification, component detection and tracking for demanufacturing and disassembly process. This is achieved by introducing a series of automated and sequential product scanning, component identification, image analysis and sorting – leading to the development of a bill of material (BOM). The produced BOM can then be associated with the relevant disassembly/demanufacture proviso. The proposed integrated image sorting and product classification (ISPC) approach can be considered as a step forward in automation of demanufacturing activities. The ISPC model proposed in this paper utilises and builds on the state-of-the-art technology and current body of research in computer-integrated demanufacturing and remanufacturing (CIDR). An appraisal of the latest research material and the factors that inhibit CIDR methods inpractice are presented. A novel solution for the integration of imaging and material identification techniques toovercome some of the existing shortcomings of automated recycling processes is proposed in this paper. The proposed product scanning and component detection ISPC software consists of four distinct models: the repertory database, the search engine, the product-attributes updater and the image sorting and classification algorithm. The software framework that integrates the four components is presented in this paper. Finally, an overall assessment of applying ISPC at various stages of CIDR processes concludes the article.University of Ibadan MacArthur Foundation Gran
