中文摘要 | 選擇適當的方法,及釐清各方法論中諸多術語的意義和代表性,而能清楚正確的運用於系統發展實務上,是任何重從事系統發展分析師必須面對的兩件高複雜度手段。要檢低複雜度,系統發展方法引進軟體工程,以仿效硬體工程成功的一些程序。而工程建立在科學知識之運用,一切科學的基礎便是數學。無論系統,工程,科學,或是數學解題都隱含高度創作活動。系統發展分析一向以其複雜無嚴格科學章法而聞敗名,引以為憾。因而能以比較科學化的系統方法,來控制發展過程中產生的複雜度,乃是當務之急。Polya的啟發式的問題解決辦法,在數學解題上貢獻良多。以此法做為系統發展分析問題,解難。以此做為實務上的邏輯思考的,觀念主軸,使系統發展法有統一的依據。如此一來,便可理解諸多看起來不同的系統發展分析法之異同。進一步知其良莠優異之因,而能把握主題,減少人為,及語言傳譯上無須莫有之複雜度。抓緊發展主過程,而大大提升系統分析設計發展專案處理的成功機會。 |
英文摘要 | Two complexities faced by any system developers are, how to choose the right methodology and how to deal with the meaning of so many terminologies used in this discipline. To make this area into more rigorous discipline, system development methodology try hard to follow and borrow idea from much established engineering disciplines. At the same time engineering benefits from sciences, and at the core of any science lays the mathematics. Therefore the system problem solving methology also can benefit much from science and engineering and mathematic problem solving if we view problem solving as a creative activity in general. Since system development is a complex problem solving process in disguise, we can benefit by borrow problem-solving techniques learned in engineering, science, and mathematics. Polya's [1,2] heuristic problem solving method for mathematics is a powerful tool in problem solving. We may use it as a central theme to any system development process and provide a unified guide to various approaches to systems. It answers many why questions of each particularity in system development process. Use these guidelines effectively eliminate much of he unnecessary complexities mentioned at the beginning faced by system implementers. Therefore, learning the control of better-focused process increases the change of a successful system project. |
