A WBS-Based Plan Changeability Measurement Model for Reducing Software Project Change Risk

Abstract—In software development process, it is necessary to face challenge for plan changes. In order to effectively reduce development risk, software project must overcome the impact of plan change. In plan change process, affected development documents and plan items should be effectively isolated and immediately modified to reduce software development risk. In software project management plan (SPMP), Work Breakdown Structure (WBS) is a critical and necessary planning tool. For this, WBS-based plan must have high isolation capability and modification flexibility to reduce plan change risk. In this paper, in order to increase WBS-based plan change capability, changeability factors are discussed, and a WBS-based Plan Changeability Measurement (WBSPCM) model is proposed. Applied the quantification mechanism of WBSPCM model, WBS-based plan changeability problem and defect can be easily identified. Used rule-based correction and improvement manner, WBS-based plan can concretely increase changeability and reduce software development risk.

Index Terms—WBS, measurement model, changeability, software development risk.
