Software & IT Service Cost-Value Engineering Excellence - »Unique knowledge and data basis. Scientific approach. Field-tested.«
Professional calculation (intelligent method-driven estimates or measurements), simulations, and optimizations require competences in 4 areas, as they all have a significant impact on effort, schedule, resources, risks, and costs independently. The precision of the results is the higher, the more transparency there is about all business / functional and quality requirements and all relevant impact factors (technologies, processes, qualifications). In case data is missing, it can easily be compensated with valid assumptions or our benchmark values.
The disregard of impact factors, e.g. by focusing solely on sizing and project size inevitably lead to wrong results in the calculation and simulation of effort, schedule, resources, risks, and costs!
