The quest for a balanced manpower capacity: different flexibility strategies examined

To cope with permanent fluctuations in demand, organizations are challenged to organize their manpower capacity in a flexible way. Different strategies of manpower planning are being used for this purpose. Using data from the 2002 Panel Survey of Organisations Flanders, we first verify to what extent temporal, contractual and functional flexibility strategies are applied in Flemish organizations. Subsequently, logistic regression is used to analyse the link between these flexible work strategies and a ‘fitting manpower capacity’. While the results show a negative association between the use of temporal or contractual flexibility measures and a balanced manpower capacity, functional flexibility seems to be positively related. The different logics in which numerical and functional flexibility proceed can be labeled as ‘curative’ versus ‘preventive’ strategies of flexibility. Further analyses discern between various interpretations of functional flexibility and assess whether different team types make a contribution to a fitting manpower capacity.

Computer-supported cooperative work:alguns temas de investigação

Os primeiros trabalhos sobre Computer-Supported Cooperative Work surgiram na segunda metade da década de 80, estabelecendo-se um campo de investigação interdisciplinar com enfoque no papel do computador e das tecnologias da comunicação no apoio do trabalho em grupo (Ishii et al., 1994). Ao abordar esta área de investigação torna-se claro que é necessário ter em conta a diversidade dos grupos e das tarefas que estes devem de utilizar, entre outros factores importantes. As implicações desta diversidade são discutidas ao nível concepção de interfaces de groupware, em que um maior envolvimento dos utilizadores nas fases iniciais parece ser necessário, e ao nível dos Sistemas de Apoio à Decisão em Grupo.
