What did we do?
Applying OO development to commercial application in certain domains e.g Telecommunications, CAD/CAM, GIS
Developed guidelines for design techniques formalised the design documentation formalised the techniques usedprovided support for the techniques
Methodology = set of design level techniques, guidelines supporting
documentation

What Did We Learn?
The textbook “methods” are not enough limited scope focus on design no single approach is complete don’t deal with the “hard” issues of project
management, quality assurance, project practicalities
Needed to develop organisation-specific OO methods Integrating OO techniques Integrating to traditional methods Make OO techniques commercially robust
Methodology = client specific methods that covered the lifecycle requirements of the particular project

A method should thus provide a standard, yet flexible, framework for developing systems, that blends engineering rigour with engineering creativity
View a method as a street directory providing the traveller with a guide to a successful outcome
Using a method permits success to be repeated (and failures to be avoided)

Hope to have provided you withAn overview of where OO methods have come
from and where they are goingAn overview of the OPEN/MeNtOR object
oriented process architectureA possible deployment strategy for process in
your organisation
Process is a critical element for effective software engineering - software engineering with object technology demands an investment in an OO software process
