A Hegelian View of SE

Hegel believed that human understanding follows a path of Thesis – this is why things happen they way they do Antithesis – the thesis fails in some important ways,

here’s a better explanation Synthesis – the antithesis rejected too much of the

original thesis, here’s a better hybrid explanation that captures the good from both thesis and antithesis

Characteristics: code-and-fix; software maintenance; non-engineering people; 1960’s “question authority” mentality; hacker culture; cowboy programmers.

Solutions:- Software Tools

- New testing and CM tools- IPSE’s- CASE

- Software Processes- “Software Processes are Software Too” - DoD STARS program on work avoidance- CMU-SEI, similar organizations in Europe and Japan - Brooks’ “No silver bullet” (1983)

- Accidental vs essential tasks (c, c, c, i) - Software Reuse

- Commercial infrastructure software reuse- OOP: Smalltalk, Eiffel, C++, Java

Other directions in 1990s: - Emphasis on Time-to-Market- Controlling concurrency in

engineering (see Boehm’s own spiral process)

- Open source development- Usability and HCI

New directions:• Agile methods• Value-based SE• Software criticality and dependability• COTS, open source, and legacy software• Model-driven development• Interacting software and systems engineering
