6 Definition of VSE Very Small Enterprise (VSE) is defined as organizations having less than 25 employees Usually not contractually obligated to follow a standard but wants to use a standard that understands VSE constraints Slide 6

7 Some data about VSE Europe 85 % of IT sector s companies have 1 to 10 employees Canada - 78 % of software development companies in the Montreal area have less than 25 employees 50% have less than 10 Enterprises with less than 10 employees represent - 93% of all companies in Europe - 56% in the US - 66% of total employment - Source - Organisation for Economic Cooperation and Development, Small and Medium Enterprises Outlook, 2002 Slide 7

8 Need for standards for VSE International standards were not written for and/or are difficult to apply in small projects, small development organizations, or companies that have between 1 and 25 employees (VSE). Implementation of current standards requires a significant critical mass in terms of number of employees, cost and time. International Life Cycle Standard ISO/IEC and guide do not explicitly address the needs of VSEs. VSEs cannot see a net benefit in establishing a software process as defined by current standards. VSE s have no or very limited ways to be recognized as an enterprise that produces quality software systems in their domain. VSEs are cut off from some economic activities. Slide 8

9 Main objectives of the new SC7 initiative Allow VSEs to be recognized as producing quality software systems without the initial expense of implementing and maintaining the entire use of a suite of Systems and Software Engineering standards or performing comprehensive assessments. Slide 9

10 Examples of Issues and Proposed Solutions by Thailand about ISO/IEC SMEs are not ready to implement the whole standard. Not all activities are suitable for SMEs operations. There is no assessment model for VSE Most software developers are not document-oriented. Standard should be broken down in to stages or levels in order to fit all sizes of SMEs. Need to modify activities to suit SMEs operation product and project based type of business. A set of checklist was developed for use by assessors. Provide packaged templates and examples for rapid documenting Source: Thai Software Industry Promotion Agency Slide 10

11 Requirements for a new standard Focus on lower levels of maturity Produce documents easy to understand Produce guidelines applicable to small teams or projects Address VSE market needs Provide examples Develop scalable profiles and guides Slide 11

12 Brief history of the project New work item proposal (NWIP) 06/2005 NWIP approval and setup of WG24 09/2005 WG24 first meeting Bari 10/2005 Consolidated requirements 05/2007 First working draft issued 01/2008 Comments deadline on WD1 04/2008 Next meeting Berlin, 19-23/05/2008 Expected publication 2010 Slide 12

13 What is an ISP? ISP International Standard Profile: - A set of one or more base standard(s) - Identification of chosen classes, conforming subsets, options and parameters of those base standards that are necessary to accomplish a particular function. NOTE - ISPs may contain normative references to specifications other than International Standards Reference: ISO/IEC TR Information technology Framework and taxonomy of International Standardized Profiles Part 1: General principles and documentation framework ISO/IEC TR freely available at the ITTF web site Slide 13
