Lesson 16

2. GANTT CHART
• a type of bar chart that illustrates a project schedule, named after its
inventor, Henry Gantt,
• He designed such a chart around the years 1910–1915.
• Modern Gantt charts also show the dependency relationships between
activities and current schedule status.

3. Network diagram
• Computer network diagram is a schematic depicting the nodes and
connections amongst nodes in a computer network or, more generally, any
telecommunications network.
• Computer network diagrams form an important part on network
documentation.

4. Radar chart
• A radar chart is a graphical method of displaying multivariate data in the
form of a two-dimensional chart of three or more quantitative variables
represented on axes starting from the same point.
• The relative position and angle of the axes is typically uninformative.

6. EARNED VALUE MANAGEMENT
• Earned Value Management (EVM) helps project managers to measure
project performance.
• It is a systematic project management process used to find variances in
projects based on the comparison of worked performed and work planned.
EVM is used on the cost and schedule control and can be very useful in
project forecasting.

7. Terms for earned value management
• Budgeted cost for work scheduled (BCWS), sometimes called the planned value.
• Budgeted cost for work performed (BCWP) or earned value.
• Actual cost of work performed (ACWP).
• Budget at completion (BAC).
• Estimate at completion (EAC) which is comprised of the cumulative to date actual cost of work performed plus the
estimate to complete the remaining work.
• Cost variance (CV) which is calculated as BCWP minus ACWP. A result greater than 0 is favourable (an under run), a result
less than 0 is unfavourable (an overrun).
• Schedule variance (SV) which is calculated as BCWP minus BCWS. A result greater than 0 is favourable (ahead of
schedule), a result less than 0 is unfavourable (behind schedule).
• Variance at completion (VAC) which is calculated as BAC minus EAC. A result greater than 0 is favourable, a result less
than 0 are unfavourable.
