Management support system (GMSS) prompt for PowerPoint
A PwC-style prompt for one slide describing an integrated management support system, sometimes labeled GMSS. It stacks four layers (sources, governed data, decision support and expert rules, executive cockpit) and adds a daily, weekly and monthly decision cadence with owners and thresholds.
Management support system architecture prompt
Fill in any highlighted fields, then copy or run it.
Create an integrated management support architecture with four layers: sources, governed data, decision support and expert rules, and executive cockpit. Add daily, weekly, and monthly cadence with source, owner, and threshold. Separate automated alerts from human approvals. Show lineage and control gaps. Do not present GMSS as a standardized product.
Why this prompt works
Layers in a fixed order
The prompt fixes four layers: sources, governed data, decision support and expert rules, then the executive cockpit. Data flows upward in one direction.
Cadence has owners and thresholds
Each daily, weekly and monthly rhythm needs a source, owner and threshold. That turns an architecture picture into an operating routine.
Alerts are separate from approvals
Automated alerts and human approvals must be shown separately, so the audience sees which decisions a system triggers and which a person signs.
Gaps are shown, not hidden
The prompt asks for lineage and control gaps and says not to present GMSS as a standardized product, which keeps the slide honest about what exists today.
Adapt it to your own deck
Name your real systems
Attach the application inventory and add "Name the actual source systems in layer one and mark any without a data owner."
Change the cadence
If your business runs on a monthly close, write "Use weekly, monthly and quarterly cadence." Keep three rhythms so the right-hand panel stays readable.
Aim it at executives or IT
For executives, add "Lead with the decisions each cadence supports." For an IT governance forum, add "Trace the data lineage for two KPIs end to end."
Management support system architecture FAQ
What is GMSS?
Here GMSS refers to an integrated management support system: a layered design that links source data, governed data, decision support and an executive view. The term is not a standard product or a single published method, which is why the prompt says not to present it as one.
Is this an official PwC template?
No. The layered management support view is a general architecture convention, and "PwC-style" describes the burgundy-to-amber design. Tosea is not affiliated with PwC.
Can ChatGPT, Claude or Gemini produce this slide?
They can describe the layers, cadence and gaps as text. Tosea uses the prompt and your attached system inventory to build the layered diagram as an editable slide that exports to PowerPoint.
PwC-style describes a common consulting framework. Tosea is not affiliated with PwC. Figures on the example slides are illustrative.
