It\u2019s happened to nearly every project manager sometime in their career. They\u2019re given the requirement to provide detailed performance reporting on a project and end up spending most of their time entering hours worked into work packages in Microsoft Project and estimating percent complete on these packages \u2013 on a daily basis. Whether the requirement for that level of reporting was real or perceived, the project manager finds that he\u2019s unable to manage the day to day activities of his project because he\u2019s too busy trying to measure the project\u2019s performance.<\/p>\n\n\n\n
When a successful company invests time, money, and other resources in a project, its primary concern is always what it is getting in return for its investment. It is the responsibility of the project manager to ensure these projects stay on schedule and within their approved budget. Performance measurement provides the project manager with visibility to make sure he is operating within the approved time and cost constraints and that the project is performing according to plan. It also alerts management if a project begins to run over budget or behind schedule so actions can quickly be taken to get the project back on track.<\/p>\n\n\n\n
As the Project Management Office (PMO) manager it is your responsibility to ensure that project performance is being captured and reported. It is also your responsibility to ensure that the level of reporting is achievable and doesn\u2019t unnecessarily overburden or distract the project managers.<\/p>\n\n\n\n
Your PMO should define the size of the work packages in your work breakdown structure (WBS). There are two typical standards; 4 to 40 hours and 8 to 80 hours. You should decide which size best fits your organization based on typical project size and level of management detail. I personally prefer the 4 to 40 as a work package cannot exceed the work of one person over a week.<\/p>\n\n\n\n
Additionally your PMO should have a standard for applying credit for work performed. There are three common approaches to this. One rule is to apply a percent complete to work packages; however, this is somewhat subjective and leads to percent completes of 99.5, then 99.6, then 99.7 \u2013 we\u2019ve all either been in this situation or seen it. A second rule is only giving credit when 100% of the work is completed on a work package, this is called the 0\/100. The work package receives no credit even if it\u2019s 3\/4 complete. This solves the problem with the previous rule; however, it leads to less accuracy when performing earned value calculations. The third option is to give 50% credit when work on a work package is started and 100% when the work is completed. This is the rule I typically follow as it gives credit for earned value management and is easy to apply in the field.<\/p>\n\n\n\n
Next, you should determine what earned value metrics you want to track and present to management. Although you can easily calculate most all earned value metrics (i.e. PV, EV, AC, SV, CV, SPI, CPI, EAC, ETC, etc) you don\u2019t necessarily need to track all these values and you definitely don\u2019t want to present them all to management. Management just needs a quick view of the project\u2019s performance using only some of these values and would be overwhelmed if they had a complete list. For most projects I track the Schedule Variance (SV), Cost Variance (CV), Schedule Performance Index (SPI) and Cost Performance Index (CPI). These four values provide a reliable measurement of the project\u2019s performance.<\/p>\n\n\n\n
Schedule Variance (SV):<\/strong> If SV is zero, then the project is perfectly on schedule. If SV is greater than zero, the project is earning more value than planned thus it\u2019s ahead of schedule. If SV is less than zero, the project is earning less value than planned thus it\u2019s behind schedule.<\/p>\n\n\n\n Cost Variance (CV):<\/strong> If CV is zero, then the project is perfectly on budget. If CV is greater than zero, the project is earning more value than planned thus it\u2019s under budget. If CV is less than zero, the project is earning less value than planned thus it\u2019s over budget.<\/p>\n\n\n\n Schedule Performance Index (SPI):<\/strong> If SPI is one, then the project is perfectly on schedule. If SPI is less than 1 then the project is behind schedule. If SPI is greater than one then the project is ahead of schedule. A well performing project should have its SPI as close to one as possible.<\/p>\n\n\n\n Cost Performance Index (CPI):<\/strong> If CPI is one, then the project is perfectly on budget. If CPI is less than 1 then the project is over budget. If CPI is greater than one then the project is under budget. A well performing project should have its SPI as close to one as possible.<\/p>\n\n\n\n You should set thresholds for these values at which their status will change to an alert. For example, if the SPI falls below 0.9 then the project\u2019s schedule should change to a yellow status. If the SPI falls further and dips below 0.8 then the project\u2019s schedule should change to a red status. Additional earned value calculations can be performed if there is a problem with the project\u2019s cost or schedule \u2013 this will give the project manager a better understanding of the problem and determining a path for correction.<\/p>\n\n\n\n Measuring project performance is an important part of project and program management. It allows the PMO and project manager to identify cost and schedule problems early and take steps for remediation quickly. It starts with setting the standards for the size of work packages, applying credit for work performed, and which earned value metrics to track, which should be included in the project\u2019s Cost Management Plan. Measuring project performance provides the organization with a clear picture of the health of its projects and can instill confidence in the project teams. Additionally, these performance measures can help the PMO establish continuous improvement initiatives in areas where projects commonly perform at lower levels. The usefulness of measuring project performance is evident and as long as organizations do not become overwhelmed with them, these measures will remain important contributors to organizational success.<\/p>\n","protected":false},"excerpt":{"rendered":" It\u2019s happened to nearly every project manager sometime in their career.
