1. Building usable software through early testing

2. Objective Show the value of testing from the beginning of the development cycle. Consensus in the industry The earlier a fault is detected and removed, the cheaper it is to fix.

3. General benefits of testing Removal of the faults and potentially fault causing situations so that they never appear in the delivered product. It is necessary then to start the testing process as early as possible.

4. Visibility of early testing Difficult to quantify the cost benefit from early testing.  The location of the error. Planning – test activity Testing and test planning must be applied at every step of the development process.

5. Early testing benefits Early years of software development  Code debug activity after the coding effort. After years of experience  The value of testing and test planning can be seen. Testing early uncovers invalid requirements and specifications.

6. Conclusion Importance of testing early in the software development process:  Quality  Test effectiveness  Project cost
