Using Object-oriented Systems Engineering to make a cup of coffee
This presentation provides a case study example of the System Development Process (SDP) without requirements. It shows how there are fewer opportunities for errors as compared to using requirements. The case study is simple yet complex enough to not only demonstrate some benefits of Object-oriented Systems Engineering OOSE (e.g., use of inheritance and templates to minimize the probability of realizing the wrong system), it also shows the tight coupling between systems engineering and project management. The presentation also points out why systems engineers should never use +/- when discussing tolerances, but use ranges instead and concludes with some lessons learned.
Let’s just stop writing requirements, we can’t write them properly anyhow
The perennial problem of poor requirements has not been solved in more than 50 years. The presentation discusses the problem, and summarizes the application of systems thinking to the problem. The presentation then proposes to dissolve the problem using an out-of-the-box requirements-free solution to the problem; Object-oriented Systems Engineering (OOSE), (MBSE on steroids) which integrates systems engineering and project management, provides several examples of Computer Enhanced Systems Engineering (CESE) and Project Management tools system development using the alternative paradigm, shows how the early states of the OOSE system development process follow the problem-solving process and concludes with the benefits of OOSE which include lower costs and shorter development times – all requirements free!
