Reducing Uncertainty in Large-Scale Agile Development Projects

Abstract

Managing uncertainty in geographically dispersed Agile software development projects remains a challenge. This paper explores methods implemented by a large-scale defense contractor team using Scrum methodologies. The project aimed to improve predictability and reduce effort estimation errors by focusing on user story writing and sprint planning practices. A key finding was the importance of establishing clear definitions for "ready" and "done" user stories, incorporating a modified INVEST method, and utilizing story writing templates. To address uncertainty during sprint planning, scales were devised to measure technical uncertainty and Subject Matter Expert (SME) availability. A decision matrix was created based on these scales to guide story inclusion within a sprint. The implemented guidelines have the potential to enhance communication, reduce rework, and improve overall project predictability for geographically dispersed Agile teams. Key Terms ⎯ Definition of "Done", Definition of "Ready", INVEST method, Scrum.
