Слайд 1

Foundation for Open Project Documentations — http://is.ifmo.ru Project Documentation in the Real World (1)


Слайд 2

Foundation for Open Project Documentations — http://is.ifmo.ru Project Documentation in the Real World (2) Commercial Software Critical Objects Control Software Main — by standards Extra — by customer needs Other By customers requirements Non commercial software Educational Good quality Other By developers wishes


Слайд 3

Foundation for Open Project Documentations — http://is.ifmo.ru Hardware Documentation vs. Software Documentation Designers and manufacturers are different people Hardware Documentation Project Documentation Design Basis Verification Results User Guide Designers and manufacturers are same people Software Documentation User Manual Developers Guide Source Code (for open source projects)


Слайд 4

Foundation for Open Project Documentations — http://is.ifmo.ru Open Project Documentation Why Project Documentation? Software quality improvement Better verification Faster and safer modification Why Open Project Documentation? Open project documentation increases freedom Better project understandability Project design borrowing Educational purposes For students For specialists


Слайд 5

Foundation for Open Project Documentations — http://is.ifmo.ru Why Only Open Project Documentation? Open = Must be available for further using and development Foundation for Open project Documentation is Free, but it is in different area comparing with Free Software Foundation or Open Source Foundation Foundation results is applicable not only for free software, but also for commercial, secret and other kinds of software


Слайд 6

Foundation for Open Project Documentations — http://is.ifmo.ru Software Project Documentation In engineering practice projects must be well-documented So on www.sourceforge.net there are not 76000 project, but much fewer The code must be based on the project documentation, not vice versa Project execution flow must be documented, not only final results


Слайд 7

Foundation for Open Project Documentations — http://is.ifmo.ru SWITCH-technology (Automata Programming) Proposed in 1991 Based on states decomposition Model-driven development Usage scope – systems with complex behavior Applicable for different type of computing devices Logic Controllers Programming Microcontrollers Microprocessors
