Scottish Water - Delivery Assurance Group: performance progress report - quarter four 2022-2023

3. Indicator of Progress of Overall Delivery

The Indicator of Progress of Overall Delivery (IPOD) provides a high-level measurement of Scottish Water's progress in delivering the Committed List for projects over £1m. It assesses the progress of these investment projects monitored across 3 delivery gates combining this information to give an overall score.

When projects are added to the Committed List, each milestone is allocated 1 point. Each quarter, the number of points achieved by reaching gates is assessed against the baseline² level for the previous quarter (lower limit) and the subsequent quarter (upper limit). These points are shown as absolute scores. Scottish Water is considered to be within the range where the number of points gained lies within the lower and upper limits.

At the end of March 2023, Scottish Water's IPOD position was back on track at 609 points, against a range of 564 to 683 points (Figure 1).

The green line in the figure above shows the aggregate of the forecast dates in the Committed List (the baseline). The solid blue bars show Scottish Water's actual position, and the light blue bars show the forecast position for future months. The green area above shows the + or – 3 months target range (i.e., the baseline from the previous and subsequent quarters respectively). Being above this shows that Scottish Water is more than 3 months ahead of the baseline and being below this shows that Scottish water is more than 3 months behind the baseline.

Figures 2, 3 and 4 below show the IPOD position at Q4 2022/2023 by individual milestone
