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 % computer projects succeeded 27% experienced cost overrun of over 20%, 15% failed altogether. 11/18/2009PAGE 3 / SET Seminar

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 IEEE Standard for Software Test Documentation /18/2009PAGE 4 / SET Seminar

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. 11/18/2009PAGE 5 / SET Seminar

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. 11/18/2009PAGE 6 / SET Seminar

LSPCM LaQuSo Software 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 11/18/2009PAGE 7 / SET Seminar

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. 11/18/2009PAGE 8 / SET Seminar

Specific criteria for High level design. [SC1] Complete: 1.Required elements. 2.Semi-formal elements. 3.Formal elements. [SC2] Uniform: 1.Uniformity within product area. 2.Compliance with company standard. 3.Compliance with industry standard. 11/18/2009PAGE 13 / SET Seminar

Specific criteria for High level design. [SC3] Conformance: 1.Manual check. 2.Automated check. 3.Formal check. 11/18/2009PAGE 14 / SET Seminar

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. 11/18/2009PAGE 15 / SET Seminar

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. 11/18/2009PAGE 16 / SET Seminar
