320 CHAPTER 6 Operations Manager Design and Planning Time Estimates The time needed per phase on any given project will vary according to the size of the organization, the organization culture, the scope of the project, and the complexity of the project. Table 6.20 provides some estimates of times needed to execute the phase for small, medium, and large organizations. TABLE 6.20 Sample Project Time Estimates Phase Design principles training Design and planning phase Proof of concept phase Pilot phase Production phase Small 1 hour 1 day N/A N/A 1 week Medium 4 hr 2 days N/A 1 week 2 weeks Large 1 day 1 week 2 weeks 1 month 1 month For some of the organization sizes, certain phases are not normally done. For example, a small organization will likely move from the design phase directly into a production deployment phase. There would be no need for a proof of concept or pilot phase with a small organization. This is reflected in the table. Summary System Center Operations Manager 2007 R2 is key to managing IT environments, and a solid design and plan are key to a successful Operations Manager infrastructure. Understanding the components of Operations Manager, their interactions, and their constraints is critical to designing and deploying an effective infrastructure. This type of functionality is instrumental in reducing downtime and getting the most out of an OpsMgr investment. Best Practices The following are best practices from this chapter: . Always create a design and plan when deploying Operations Manager, even if it is a simple one. . Take future expansion and relevance of hardware into account when sizing servers for OpsMgr deployment.
