Delivery Assurance Group (DAG) report: quarter 1 2022 to 2023

Section 2: 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^[1]. It assesses the progress of these investment projects monitored across 3 delivery gates^[2] 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 baseline^[3] 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 June 2022, Scottish Water's IPOD position was on track at 371 points, against a range of 314 to 483 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., is the baseline from the previous and subsequent quarters respectively). Being above this shows that Scottish Water are more than 3 months ahead of their baseline and being below this shows that Scottish water are more than 3 months behind their baseline.

Figures 2,3 and 4 below show the IPOD position at Quarter 1 2022-2023 by individual milestone:

Year to date performance on the Start on Site milestone is in the top half of the range.

Year to date performance on the Gate 100 (Project Acceptance) milestone is outwith the range (Figure 3) where 157 points were achieved to date with the target range being 181 -230. The realisation of risks for a number of projects has resulted in longer forecast delivery times on the Wastewater and Water portfolios which have moved the total position out with the target range. Explanation of this movement can be found in Sections 4 & 5. After the DAGWG full details of the projects impacted on the water portfolio have been explored bi-laterally between SW and DWQR.

Year to date performance on Gate 110 (Financial completion) is at the middle of the range (Figure 4) where 139 points were achieved to date with the target range being 79 –170.
