3. Introduction • Software project failure: • Customer requirements not met. • Delivery deadline not met. • Actual cost higher than estimated cost. • Too many errors. • Statistical facts: The Standish group reported in 2003 • 34% computer projects succeeded • 27% experienced cost overrun of over 20%, • 15% failed altogether. / SET Seminar

4. Introduction • Software Certification can be used to prevent these failures and to improve the quality of the software product. • “Certification is a process of confirming that a system or a component complies with its specified requirements and is acceptable for operational use.” • IEEE Computer Society. IEEE Std 829-1998. IEEE Standard for Software Test Documentation 1998 / SET Seminar

5. Certification • Benefits of certification: • Helps to obtain certainty and confidence in software artifacts. • Offers an advantage over the competition. • Gives more confidence to the prospective buyers. • In outsourcing projects, an independent party can determine that deliverables are acceptable. / SET Seminar

6. Certification for an Offshore project • Outsourcing process is threatened by the missing context information at handover moments: • Requirements • High level design • Source code • End system • Certification at handover moments helps to achieve that documents are • consistent • made in the right way. / SET Seminar

7. LSPCM • LaQuSoSoftware Product Certification Model. • A rule based software product certification model. • Model consists of 6 product areas: • Context description • User requirements • High Level design(HLD) • Detailed design • Implementation • The tests / SET Seminar

8. LSPCM • In order to analyze the artifacts LSPCM defines three Certification Criteria(CC) for all Product Areas: • [CC1] Completeness – All required elements in the Product Area should be present. • [CC2] Uniformity – The style of the elements in the Product Area should be standardized. • [CC3] Conformance – All elements should conform to the property that is subject of the certification. / SET Seminar

9. Certification criteria achievement levels / SET Seminar

10. LSPCM – Certification Levels • Initial • Manually verified • Automated verified • Model verified • Formally verified / SET Seminar

11. Objectives • Improve LSPCM - Applying LSPCM 1.1 to the HLD of an offshore project. • Scaling of certification and specific criteria for high level design. • Incremental / SET Seminar

12. Process flow / SET Seminar

13. Specific criteria for High level design. • [SC1] Complete: • Required elements. • Semi-formal elements. • Formal elements. • [SC2] Uniform: • Uniformity within product area. • Compliance with company standard. • Compliance with industry standard. / SET Seminar

14. Specific criteria for High level design. • [SC3] Conformance: • Manual check. • Automated check. • Formal check. / SET Seminar

15. Issues • Some issues common to all models in G with respect to HLD: • Missing High-level documents such as • component model. • flowcharts. According to an experimental comparison by D.A.Scanlon, it is considered very helpful to introduce flowcharts to describe process flow, as it increases comprehension of the program. • Missing translation document. • Ambiguous use cases. / SET Seminar

16. Deliverables • Analysis report on model 2 • Analysis report on model 3 • Reports on interviews with project experts. • List of suggestions what LSPCM criteria are of less importance and why. • List of suggestions how LSPCM can be improved for outsourcing projects. / SET Seminar
