Conceitos
The factory is an organization inhabited by people
engaged in a common effort, work is organized
one way or the other, standardization is used for
coordination and formalization, and
systematization is important, but there will be
several options for the design of a particular
software factory
[Aaen, Botcher, Mathiassen, Software Factories, 1997]
Conceitos
Much of our knowledge of how to accomplish our
purposes is not articulate but tacit
The whole field of software development
methodology remains in ferment, with new
methodologies growing up amid high hopes, and
then fading in disappointment
Capital goods are, in their essence, embodied
knowledge
[Howard Baetjer, jr. Software as Capital, 1998]

• Context
– In which setting was the approach developed?
• Objective
– Which goals are pursued and which specific problems
are sought to be solved?
• Strategy
– How should these goals be achieved?
• Organization
– What is the proposed design of the software factory?
• Implementation of improvement
– How should the improvement efforts be implemented?
...conclusões...
The four approaches are important
contributions towards this goal. At the same
time the approaches individually may lead
to unfortunate illusions. Learning from the
relative strengths and weaknesses between
the approaches may help us avoid becoming
victims of these illusions
