Title: Software Capacity Planning: A Methodology For A Portfolio Of High Technology Product Development Projects
Author: Malhotra, Rajiv
Abstract: High technology product development projects make extensive use of engineering software during the product development process . The suite of engineering software tools deployed during product development represents a significant portion of the product development costs . The ability to forecast the engineering software license capacity required to support product development plans is crucial for budgeting , return on investment (ROI ) calculations , contract negotiations with the software suppliers , and the provision of an IT infrastructure necessary to support the execution of the software tools . This research shows that the usage of engineering application software in high technology is cyclical due to the characteristics of high technology product development . A rigorous methodology to compute the cycle boundaries based on usage history is proposed . Information of the usage cycles is used to modify the existing trend forecast to increase the prediction accuracy of future usage predictions . Data of the current usage of the projects in execution is then used to forecast the overall software capacity needed to support all current projects . Cyclic usage patterns also predict how the usage is expected to change in the future for the time period under study . Usage data is collected for the three main projects concurrently in execution . Of the three , one of the projects goes through its full development cycle . In this research we show (a ) a rigorous methodology using Fourier analysis to extract the cyclical variations of the project that goes through its full development cycle and (b ) the application of the cyclical variations to a trend forecast to improve the quality of the forecast .Single project forecasts are then combined to generate an overall engineering software capacity forecast for the enterprise . All engineering software licenses for both project and non -project work are shared by the enterprise from a central license pool . To determine the enterprise capacity requirement , the relationship between the key individual projects and the total usage is determined and used to predict future capacity .
