Chapter 7. Warehouse Management and Support Processes Warehouse Management and Support Processes Warehouse management and support processes are designed to address aspects of planning and managing a data warehouse project that are critical to the successful implementation and subsequent extension of the data warehouse. Unfortunately, these aspects are all too often overlooked in initial warehousing deployments. These processes are defined to assist the project manager and warehouse driver during warehouse development projects. Define Issue Tracking and Resolution Process During the course of a project, it is inevitable that a number of business and technical issues will surface. The project will quickly be delayed by unresolved issues if an issue tracking and resolution process is not in place. Of particular importance are business issues that involve more than one group of users. These issues typically include disputes over the definition of business terms and the financial formulas that govern the transformation of data. An individual on the project team should be designated to track and follow up the resolution of each issue as it arises. Extremely urgent issues (i.e., issues that may cause project delays if left unresolved) or issues with strong political overtones can be brought to the attention of the Project Sponsor, who must use his or her clout to expedite the resolution process. Figure 7-1 shows a sample issue log that tracks all the issues that arise during the course of the project.

Indicate the priority level of the issue: high, medium, or low. Low-priority issues that are left unresolved may later become high priority. The team may have agreed on a resolution rate depending on the urgency of the issue. For example, the team can agree to resolve high-priority issues within three days, medium-priority issues within a week, and low-priority issues within two weeks.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
