  • 1. Software Development using ISO/IEC 29110 Engineering and Management for ISVs <br />KritKamtuoMicrosoft Innovation Center Outreach – ManagerE-Saan Software Park , KhonKaen University.<br /><br /><br />
  • 2. History<br />Thailand industry recognizes very small entities-VSE for their valuable products. As software quality increasingly becomes a subject of concern, and as process approaches are maturing and earning the confidence of companies, the use of ISO international standards is distributing in organizations of all sizes. <br />
  • 3. History<br />However, these standards were not written for VSE and are consequently difficult to apply in such settings. A new ISO/IEC JTC1/SC7 Working Group has been established to address these difficulties by developing profiles and providing guidance for compliance with ISO software engineering standards.<br />
  • 4. Complianced Countries<br />
  • 5. Basic Profile<br />Rationale of the Basic Profile<br />To define a software development and project management guide for a subset of processes and outcomes of ISO/IEC 12207 and ISO/IEC 15289 products, appropriate for characteristics and needs of VSEs.<br />The reason to include project management is that VSEs’ core business is software development and their financial success depends on project profits.<br />Applicability<br />Describes software development of a single application by a single project team with no special risk or situational factors.<br />The project may be to fulfil an external or internal contract. <br />The textisextractedfrom ISO/IEC 29110<br />
  • 6. Basic Profile Guide Processes<br />PM process uses the customer’s statement of work to elaborate the project plan. The PM project assessment and control tasks compare the project progress against the project plan and actions are taken to eliminate deviations or incorporate changes to the project plan. The PM project closure activity delivers the software configuration, produced by SI, and gets the customer’s acceptance to formalize the end of the project. A project repository is established to save the work products and to control its versions during the project<br />The execution of the SI process is driven by the project plan. SI process starts with an initiation activity of the project plan review. Project plan will guide the execution of the software requirements analysis, software architectural and detailed design, software construction, software integration and test, and product delivery activities<br />The textisextractedfrom ISO/IEC 29110<br />
