Software Cost Estimating for Iterative and Incremental Development Programs

Software/Hardware Track



Iterative and Incremental Software Development processes are at the heart of a cyclic software development process. Iterative and Incremental Software Development processes evolved in response to the weaknesses of the traditional waterfall model. Iterative and Incremental Software Development start with an initial planning and ends with deployment with the cyclic interactions in between. The goal is to deliverer what the user needs at the end of the process, not only what was envisioned at the beginning of the process. Iterative and incremental development is an essential part of the Rational Unified Process, Extreme Programming, and generally the various agile software development frameworks. This presentation will address the cost estimating and management issues faced by the Department of Navy as iterative and incremental software development becomes more pervasive in traditional and Service Oriented Architecture (SOA) programs. The key issues are determining size metrics for each increment, estimating in the agile environment, developing reliable historic cost databases and relationships. Often these projects become level of effort projects because management lacks the metrics to project requirements of the next phase/increment of the project. This presentation will present a complexity and functionality matrix that can be used by management to assess the requirements of the next increment of the program.

Jennifer Swartz is an Associate with Kalman & Company, Inc. with four years of experience in Department of Defense (DoD) cost estimation. She recently earned her Professional Cost Estimator/Analyst (PCEA) certification, and will gain her Certified Cost Estimator/Analyst (CCEA) certification in one year. She developed the Joint Program Executive Office (JPEO) Chemical and Biological Defense (CBD) pilot Will-Cost/Should-Cost estimates for the Common Analytical Laboratory System (CALS), and more recently contributed to the JPEO CBD Official Should-Cost Procedures and Guidelines. Ms. Swartz created the dynamic Marine Air-Ground Task Force (MAGTF) Command and Control (C2) Systems and Applications (MC2SA) dynamic cost model in Microsoft Excel, which accounts for multiple ‘what-if’ scenario’s for the Tactical Service Oriented Architecture (TSOA) software program. She is a 2007 Cum Laude graduate of The Ohio State University, where she majored in Finance and German and was the 2010 Society of Cost Estimating and Analysis (SCEA) Washington Metro Chapter Junior Analyst of the Year.
