Usage of Crystal ball tool to run PPM Models - As Planning and Quality Tool for Agile-Scrum Development Projects

Process Performance Models (PPM) are used to improve the consistency of interpretation of CMMI (Capability Maturity Model – Integration) quality process for high maturity and capability. Process-performance models provide insight into the effect of process changes on process capability and performance. PPM models also can be used to predict performance of process changes, thus, facilitating cost benefit analysis. Agile development process is an iterative, incremental method of managing the design and build activities of engineering. The Agile development seeks alternatives to traditional project management. Agile approaches help teams respond to unpredictability or changes through incremental, iterative work cadences and empirical feedback. In the present analysis, an attempt was made to analyze certainty of achieving Sprint Planning goals of agile development projects using the PPM models. Crystal ball tool was used to run the PPM model for predicting certainty of achieving sprint planning effort during the initial sprint (during sprint planning). If the certainty is achieved greater or equal to 80%, then possibility of achieving sprint planning effort within the limit set (capacity planning for effort) in the sprint planning is higher. This model also can be used for prediction of Quality (i,e Defect Density) for sprint testing defects and UAT (User Acceptance Testing) defects.
