Project duration and staffing

  1. 2. <ul><li>As well as effort estimation, managers must estimate the calendar time required to complete a project and when staff will be required </li></ul><ul><li>Calendar time can be estimated using a COCOMO 2 formula </li></ul><ul><li>TDEV = 3 ´ (PM)(0.33+0.2*(B-1.01)) </li></ul><ul><li>PM is the effort computation and B is the exponent computed as discussed above (B is 1 for the early prototyping model). This computation predicts the nominal schedule for the project </li></ul><ul><li>The time required is independent of the number </li></ul><ul><li>of people working on the project </li></ul>
  2. 4. <ul><li>Staff required can’t be computed by diving the development time by the required schedule </li></ul><ul><li>The number of people working on a project varies depending on the phase of the project </li></ul><ul><li>The more people who work on the project, </li></ul><ul><li>more total effort is usually required. </li></ul><ul><li>A very rapid build-up of people often correlates with schedule slippage </li></ul>
