Using Object-oriented Systems Engineering to make a cup of coffee

Date: 2022-11-08

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.
