Creating the best performing xCelerated Composition Platform (xCP) systems to address your<br />
business requirements involves; 1) designing and configuring the software to maximize throughput<br />
and minimize response time, and 2) sizing your hardware components. This document focuses on<br />
designing and configuring the software. Chapter 2, Planning Capacity and Sizing provides summary<br />
information on capacity planning and system sizing. The following chapters provide detailed<br />
information on designing and configuring high performing xCP systems:<br />
• Chapter 3, Maximizing Process Throughput<br />
• Chapter 4, Designing the Application<br />
• Chapter 5, Designing Reports<br />
• Chapter 6, Configuring System Components<br />
• Chapter 7, Measuring <strong>Performance</strong><br />
• Chapter 8, Maintaining the Repository and BAM Databases<br />
• Chapter 9, Troubleshooting<br />
Software development lifecycle<br />
Figure 1, page 11 illustrates a typical Software Development Life Cycle (SDLC). <strong>Performance</strong> tuning<br />
opportunities exist at every stage of the development process.<br />

Business case — Expectation setting and volume metrics characterize the business case phase. Make<br />
sure that realistic system expectations are defined up front. For example, it is unrealistic to expect<br />
being able to fetch 5 TB digital movie master file in 2 minutes. Carefully define current and future<br />
business transaction volumes as they have a significant impact on capacity planning.<br />
