  1. Welcome to software construction

  2. 1.1 What is Software Construction? • It is a very complicated process, includes:

  3. 1.1 What is Software Construction? (cont.) • “Construction”: “coding” or “programming”

  4. 1.2 Why Is Software ConstructionImportant? • Construction is a large part of software development • Depending on the size of the project, construction typically takes 30 to 80 percent of the total time spent on a project. • Construction is the central activity in software development • Requirements and architecture • Construction • System testing • With a focus on construction, the individual programmer’s productivity can improve enormously • A classic study by Sackman, Erikson, and Grant showed that the productivity of individual programmers varied by a factor of 10 to 20 during construction (1968).

  5. 1.2 Why Is Software ConstructionImportant? • Construction’s product, the source code, is often the only accurate description of the software • The only documentation available to programmers is the code itself. • Requirements specifications and design documents can go out of date, but the source code is always up to date. • Construction is the only activity that’s guaranteed to be done • Requirements and architectural design before construction begins. • System testing after construction. • Real-world projects often skip requirements and design tojump into construction. They drop testing because they have too many errors to fix and they’ve run out of time. • No matter how rushed or poorly planned a project: you can’t drop construction • Improving construction is a way of improving any software-development

  6. 1.3 How to Read This Book • Read books cover to cover: go to Chapter 2. • Specific programming tips: begin with Chapter 6. • You’re not sure whether any of this applies to you, begin with Section 3.2.
