cecef8bfa812 early version, mainly the outline

parents:

33 Today, few software designers are aware of these concepts,
cecef8bfa812 early version, mainly the outline
meillo@marmaro.de
parents:

34 and thus most modern software is limited and does not use software leverage.

42 Building a software is a process from an idea of the purpose of the software
cecef8bfa812 early version, mainly the outline

parents:

43 to the finished program.
cecef8bfa812 early version, mainly the outline

44 No matter \fIhow\fP the process is run, two things are common:
cecef8bfa812 early version, mainly the outline

45 the initial idea and the release.

46 But the the process inbetween can be of any shape.

47 The time of release and the maintainance work after the release are ignored here, for the moment.

49 The process of building splits mainly in two parts:
cecef8bfa812 early version, mainly the outline

50 the planning of what and how to build, and implementing the plan by writing code.
cecef8bfa812 early version, mainly the outline

51 This paper focuses on the planning \(en the design \(en of software.

53 Though the Unix Philosphy does recommend how the software development process should look like,

54 this shall not be of matter here.
