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
• complexity• team work• competition on the
market– reliability – time limit
• cost estimation• optimization
requirements analysis
design
Implementation
testing
Integrated project management optimization
Model based cost prediction
Already finished projects
Product Envi-ronment
Techno-logy
Humancapacity
Extrapolation
Main formula
Integrated project management optimization
Model based cost prediction• Parameters influencing the effort:
product
platform
person
project
- size- complexity- reliability
-progr. language exp.- main storage- execution time
- capability- experiment
- 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
Requirementsanalysis
Integrated project management optimization
Design
• Possible solution versions– formal description
• automated cost estimation – refined models– refined predictions
• component integration
Requirementsanalysis
Design
Integrated project management optimization
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
