Little research has been conducted to date on the specific topic of the tailoring of systems development methods. Two related research areas—contingency factors research and method engineering—have exhibited a primarily deductive research focus. In contrast, this paper presents an inductive study into method tailoring in practice within the Motorola organisation. The findings illustrate the sophisticated multi-level tailoring process at industry, organisational and project level. The multi-level tailoring process depicted here overcomes the problem of trying to comprehensively tailor a method in a development environment in which time is not available for a lengthy tailoring process on each project. The paper builds on both the contingency factors and method engineering streams, and also contains useful practical guidelines for practitioners.
