What makes you professional

1
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.

2
Computer technology in organisation

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

Performance and management

• 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.

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.

7
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.

8
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)

9
Characteristics of system development methods.

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

10

• 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.
