What makes you professional

Experience plays the leading part in practical system development.

The professional system developer is openminded towards the experiencee of other people.

Methods and theories can never replace experience but can inspire.

Computer technology in organisation

A systemdevelopmentproject is limited in time and is directed at a specifik part of the organisations computer-based systems.

It is important to have a method-independed understanding of systemsdevelopment.

4 basic components- A process – a system development project contains a process limited in

time, resulting in specific products and services. Your 2 semester project was an process.

- A activity – what we actually do – programming a module.- A function – denotes the intended result of one or more processes

regardless of how the processes actually take place. Analyse, design and planning could be examples of functions.

- A task – a more concrete description of an intension. A function can typically be concretized into a number og tasks directly indicating the disired result. – revising an overall projectplan.

Action

Performance – making the system

Analysis function – user organisation technical options and existing design proposals. Result understanding the user organisation.

Design function – formulation of one or several visions of a disired change in the organisation. Result description of programs, computer systems and working processes.

Realisation function – computer systems and programs changed working practices, qualifications and attitides in the user organisation.

Management – leading the project

Evaluation function – is directed at the process itself and the current plans.

Planning function – establishing the project + overall planning and detailed planning.

Regulation function – results in changes in the process.

General functions

Decision making (deal with both the process and the product. Some decissions are made internally in the projectgroup, or involve external groups or people. Decissions may take time and they may delay the project).

Communication (dialog by people or email)

Socialization (projects internal and informal contracts)

Characteristics of system development methods.

Application area Perspective Guidlines - techniques - tools - principles of organisation

Application area (big or small system, how many users, how many developers. Equipment applied).

Perspective(impose a specif perspektive on its users. The perspective is always reflected in the guidelines.)

Guidelines - techniques(a technique indicates how a specific working

process can be performed. (how to fish with traps) - tools (a technique employes a number of tools, ex javaprogramminglanguage). - principels of organisation (indicate how the various

people and groups should cooperate, and how the always limited ressources should be employed and allocated)

Assignment

You schall from fig 3.3 page 12 give an analyse of the main compenents af system development.

From every component give exampels from your 2.semester project. I also want examples of general decissionmaking, communication and socialization.
