## Analysis

### S-curve Analysis

Initial examination of the S-curves generated above reveal the following about the status of the project.

• The project has grown in scope. (The Target S-curve finishes above the Baseline S-curve)
• The project has slipped. (The Target S-curve finishes to the right of the Baseline S-curve)
• The project is behind schedule. (The Actual S-curve sits below the Target S-curve at the Cut Off Date)

### Project Growth

Analysis of the Baseline and Target S-curve data reveals the project has grown in scope by 12 man-hours, or 14.29%.

• i.e. Growth = Target MHs - Baseline MHs = 96 - 84 = 12
• i.e. Growth % = (Target MHs / Baseline MHs - 1) x 100% = (96 / 84 - 1) x 100% = 14.29%

### Project Slippage

Analysis of the Baseline and Target S-curve data reveals the project has slipped by 1 day, or 20.00%.

• i.e. Slippage = Target Duration - Baseline Duration = 6 - 5 = 1
• i.e. Slippage % = (Target Duration / Baseline Duration - 1) x 100% = (6 / 5 - 1) x 100% = 20.00%

### Project Progress

According to MS Project, based on the Production Schedule the project is 50% complete. MS Project calculates percentage complete based on durations, and does not take into account man-hours assigned to each task. Analysis of the Actual and Target S-curve data reveals the project is 53.13% complete as of the Cut Off Date, while the project should be 59.38% complete.

• i.e. Actual % Complete = (Actual YTD Man Hours @ Cut Off Date / Target Man Hours) x 100% = (51 / 96) x 100% = 53.13%
• i.e. Target % Complete = (Target YTD Man Hours @ Cut Off Date / Target Man Hours) x 100% = (57 / 96) x 100% = 59.38%
