3.8 Solution Assurance Review Some level of Solution Assurance Review (SAR) should be performed for all IBM solutions. The level of SAR (self, peer, or expert) should match the complexity of the solution. For example, simpler solutions may need only a self review. However, a combination of the customer environment risk combined with the complexity of the solution may require that an expert level SAR take place, facilitated by a Quality Assurance practitioner and supported by a team of technical experts. If a solution contains four or more Enterprise X-Architecture servers (currently x360, x365, x445 and x455), then an expert SAR is mandatory. For further information on what is required, refer to the Solution Assurance Web sites. EMEA and Americas information is available. Procedures for Asia Pacific countries are currently in development. 3.8.1 Trigger Tool The SAR Trigger Tool provides a recommendation on the level of Quality and Solution Assurance that will be required. It is available from one of the Solution Assurance Web sites. The three levels are: Expert - For technically challenging, high-risk solutions - Process dictates expert personnel's participation - Formal, rigorous Peer - For low-to-medium risk solutions - Informal, inexpensive Self - For low-risk solutions - Informal, inexpensive 3.8.2 Electronic Solution Assurance Review (eSAR) There is also an eSAR tool available to help you establish whether you require an expert review.
