Method Engineering is defined as the engineering discipline to design, construct, and adapt methods, techniques and tools for systems development. The primary focus of the course is to apply meta-modeling for the assembly and evaluation of methods; the adaption of concepts and rules for techniques;...

, 1. Introduction
Issues in Information Systems domain: 1) How? 2) Which method? 3) What model? 4)
What tool? 5) How to get more mature?
Response to these issues: many methods and techniques, although there is no generic
answers. It al depends on the situation: project, company, people, budget, timing,
technology & platforms. Therefore, a study and adaption of methods and tools is needed.
Scientific studies in Method Engineering:
- Formal description of methods
- Identification of method fragments
- Situational configuration of project specific methods
- Method comparison
- Incremental method evolution
- Formalization of method properties
- Derivation of tool support
Method definition
A method is an approach to perform a systems development projects, based on a specific
way of thinking, consisting of directions and rules, structured in a systematic way in
development activities with corresponding development products.
Comes from Methodos, Greek for: way of investigation.
A method consists of phases. 1) Preparation phase, 2) several execution phases, and 3)
completion phase. Every phase end is a major deliverable or a go/no-go decision.
A phase consists of activities. Activities may consist of sub-activities, 3 or 4 levels of sub-
activities is sufficient. An activity consists of a set of basic activities to be executed possibly
conditionally in some order.
