In this paper, we propose the use of fine-grain processmodelling as an aid to software development. We suggestthe use of two levels of granularity, one at the level of theindividual developer and another at the level of therepresentation scheme used by that developer. Theadvantages of modelling the software development processat these two levels, we argue, include respectively: (1) theproduction of models that better reflect actualdevelopment processes because they are oriented towardsthe actors who enact them, and (2) models that arevehicles for providing guidance because they may beexpressed in terms of the actual representation schemesemployed by those actors. We suggest that our previouslypublished approach of using multiple ?ViewPoints? tomodel software development participants, the perspectivesthat they hold, the representation schemes that theydeploy and the process models that they maintain, is oneway of supporting the fine-grain modelling we advocate.We point to some simple, tool-based experiments we haveperformed that support our proposition.
