  4. Ilusões fábrica de softwareprodução em massa padronização, formalização, especialização, controle  produção de software em massa [o que fazer?]

  5. 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]

  6. 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]

  7. 4 idéias: contribuições e ... • Japonesa (1981,1987) • SWB – Software Work Bench • Européia (1991,1992) • ISDE – Integrated Software Development Environment • Norte-Americana – experiência produção (1989,1993) • Norte-Americana – níveis de maturidade (1990,1993)

  8. ...Análise Comparativa... • 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?

  9. ...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

  10. ... Ilusões... ?...? • Zezinho? • Patinho Feio? • Software? • Standish Group – Chaos Report • Failed – 40% (1996)  23% (2000)
