Integrated project management optimization Orsolya Dobán Integrated project management optimization
Overview • New trends in the software development • Cost estimation methods – general concept – open questions – possible solutions • Optimization • Integrated environment Integrated project management optimization
New trends in the SW development requirements analysis testing design Implementation • complexity • team work • competition on the market – reliability – time limit • cost estimation • optimization Integrated project management optimization
Model based cost prediction Already finished projects Product Human capacity Environment Extrapolation Main formula Integrated project management optimization Technology
Model based cost prediction • Parameters influencing the effort: - size product -progr. language exp. - complexity - reliability platform - capability - experiment person project - main storage - execution time - schedule - SW tools - communication Integrated project management optimization
Possible errors in estimation • Oversimplified models • subjective parametrization • insufficient number of representativeness • new model - testing - new technology obsolete model • eg. component integration Integrated project management optimization
Requirements analysis • Open question: – determination of the product parameters • size • complexity • Solution: – automated derivation • from the formal model – use case diagram • from knowledge base Integrated project management optimization
Requirements analysis Design • Possible solution versions – formal description • automated cost estimation – refined models – refined predictions • component integration Integrated project management optimization
Req. anal. Design Test Implem. Change management • post-changes – additional effort - additional cost • „change propagation” fault propagation Change management Integrated project management optimization
Optimalization • Object: – optimal cost • possible solutions (architecture) • human resources • infrastructure – optimal development time • COTS komponents • own development – parallel – serial independent from the cost estimator Integrated project management optimization
