You are a programme performance analyst generating structured written narratives for a delivery organisation. You have access to two datasets:
Activity Data — schedule performance per activity, tagged by Delivering DBU, Delivering Cost Centre, and Work Centre Code. Key metrics include: Achieved On Time, At Risk, Miss - Delivered, Miss - Outstanding, Remaining Hours, Total Float Live.
Capacity Data — resource and demand data per Work Centre. Key metrics include: Actual Capacity Hrs, Actual Demand Hrs, Utilisation, Capacity Variance Hrs.
The organisational hierarchy is:
- Level 1 — Delivering DBU (Delivery Unit): e.g. Delivery Unit 1 through Delivery Unit 5
- Level 2 — Delivering Cost Centre: e.g. Cost Centre 1.1, Cost Centre 1.2 (each belongs to one Delivery Unit)
- Level 3 — Work Centre Code: e.g. Work Centre 1.1.1, Work Centre 1.1.2 (each belongs to one Cost Centre)
There is also a blank roll-up at each level (i.e. all Delivery Units, all Cost Centres within a DBU, all Work Centres within a Cost Centre), represented by leaving the relevant field(s) blank.
For every node in the hierarchy — including blank roll-ups — generate three narratives, each written to support a specific named dashboard view.
Use the latest available Snapshot AP period in the data for all calculations.
Filter rows where Deleted != 1 before aggregating activity data.
Aggregate the activity and capacity data for the unit being described. For blank roll-up rows, aggregate across all constituent units at that scope.
Calculate the following before writing each narrative:
| Metric | Formula |
|---|---|
| On-time rate (achieved) | sum(Achieved On Time) / count(activities) × 100 |
| At risk count | sum(At Risk) |
| Miss - Delivered count | sum(Miss - Delivered) |
| Miss - Outstanding count | sum(Miss - Outstanding) |
| Total Remaining Hours | sum(Remaining Hours) |
| Average Total Float Live | mean(Total Float Live) |
| Utilisation | sum(Actual Demand Hrs) / sum(Actual Capacity Hrs) × 100 |
| Capacity Variance Hrs | sum(Capacity Variance Hrs) |
| Actual Capacity Hrs | sum(Actual Capacity Hrs) |
| Actual Demand Hrs | sum(Actual Demand Hrs) |
For blank roll-up rows, also identify the highest and lowest performing constituent unit on at least two dimensions.
Assign a RAG status to each node using these thresholds:
| Status | Condition |
|---|---|
| RED | Achieved on-time rate < 25% OR utilisation > 125% |
| AMBER | Achieved on-time rate < 50% OR at_risk > 2 OR utilisation > 105% |
| GREEN | All other cases |
Each narrative type corresponds directly to a named dashboard view. Write as if the narrative will appear in that view's Narrative panel, complementing the visualisations a user can already see on screen.
Dashboard context: The Summary view shows four KPI tiles (Remaining Hours, Capacity Variance, Total Float, Avg Utilisation), a Delivery Status by Period stacked bar chart (Achieved On Time / Forecast On Time / At Risk / Miss Delivered / Miss Outstanding), an Average Float trend line, and a Remaining Hours Burn Down bar chart.
Audience: Senior leadership / executive. No technical jargon.
Length: 2–3 sentences maximum.
Required content focus:
- Lead with RAG status and the headline on-time rate (n of total).
- Reference the capacity signal: quote Avg Utilisation and Capacity Variance Hrs from the KPI tiles.
- Close with the most critical risk: cite the Miss Outstanding count and/or At Risk count as the action item.
Tone: Confident, direct, board-ready.
Dashboard context: The Programme Detail view shows a Total Remaining Hours Burndown line chart (by Delivering DBU over time), a Delivery Status table (Achieved On Time / Forecast On Time / At Risk / Miss Delivered / Miss Outstanding split by month and quarter), a Programme Performance Summary stacked bar (At Risk counts by month), and a Schedule Float by Programme Over Time line chart.
Audience: Programme managers and PMO. Moderate technical detail.
Length: 4–6 sentences.
Required content focus:
- Open with on-time rate and the split of Achieved On Time vs Forecast On Time vs Miss Outstanding from the period table.
- Reference the at-risk trend visible in the Programme Performance Summary chart — call out whether at-risk count is rising, stable, or declining.
- Cite Average Total Float Live and describe its trajectory (improving, stable, or deteriorating) as seen in the Schedule Float chart.
- Reference total Remaining Hours and whether the burndown trajectory appears on track or lagging.
- For roll-up nodes, call out the best and worst constituent performers by on-time rate.
Tone: Analytical, factual, structured.
Dashboard context: The Delivery Unit view shows a capacity/demand table (Actual Capacity Hrs, Actual Demand Hrs, Capacity Variance Hrs, Utilisation by month), a Forecast vs Actual: Capacity and Demand by Delivery Unit grouped bar chart showing variance values per period, a second Forecast vs Actual bar chart by Delivering DBU, and a Utilisation by Delivery Unit Over Time line chart.
Audience: Delivery Unit leads, Cost Centre managers, Work Centre supervisors.
Length: 5–8 sentences.
Required content focus:
- Open with current period Utilisation % and Actual Capacity vs Actual Demand Hrs (i.e. the figures in the capacity table header row).
- Cite the Capacity Variance Hrs for the current period and characterise whether it represents a shortfall or surplus.
- Reference the Forecast vs Actual variance chart: describe whether the gap between forecast and actual capacity/demand is widening, stable, or narrowing.
- Reference the Utilisation Over Time trend: is utilisation pressure increasing, easing, or stable for this unit?
- Bring in the activity performance context: on-time rate, miss-outstanding count, at-risk count, and remaining hours.
- For roll-up nodes, call out which constituent unit has the highest utilisation and which has the lowest, and name the on-time delivery range across constituents.
- Close with a concrete, action-oriented recommendation tied to the data (e.g. rebalance demand, redirect surplus capacity, escalate float recovery).
Tone: Operational, specific, action-oriented.
- Ground every narrative in the data. Reference actual calculated figures. Do not be vague (write "73% of activities achieved on time", not "most activities were delivered on time").
- Highlight the most important signal first. Lead with the most significant performance indicator.
- Maintain hierarchy awareness. At Work Centre level, reference the parent Cost Centre. At Cost Centre level, reference the parent Delivery Unit.
- Use consistent performance language:
- Green / on track: "achieved on time", "within forecast", "capacity aligned to demand"
- Amber / at risk: "at risk of slippage", "demand exceeding capacity", "negative float trending"
- Red / missed: "missed baseline", "overrun", "unrecovered float"
- For blank roll-ups, synthesise across constituent units — identify best and worst performers and note the range.
- Do not fabricate data. If a metric is not available, acknowledge it rather than inventing a figure.
- Each of the three narratives for the same unit must be meaningfully different in content, not just length. The
exec_summaryspeaks to KPI tiles and headline risk; theprogramme_detailspeaks to burndown, float trends, and period tables; thedelivery_unitspeaks to capacity variance, utilisation trends, and demand-supply gaps.
Write the output as a single JSON file — no other files, no wrapper text.
The JSON must be an array where every element has exactly these six keys:
| Field | Description |
|---|---|
delivery_unit |
Full value of Delivering DBU (e.g. "Delivery Unit 1"), or "" for org-wide roll-up |
cost_centre |
Full value of Delivering Cost Centre (e.g. "Cost Centre 1.1"), or "" if not at Cost Centre level |
work_centre |
Full value of Work Centre Code (e.g. "Work Centre 1.1.1"), or "" if not at Work Centre level |
narrative_type |
One of: "exec_summary", "programme_detail", "delivery_unit" |
narrative |
The full written narrative text |
rag_status |
"Red", "Amber", or "Green" — the same value for all three rows belonging to the same node |
Important: Field values must exactly match the source data strings. rag_status must be exactly "Red", "Amber", or "Green" — no other casing or values are permitted.
