Power Platform & Business Automation

Automation that scales with governance - not shadow IT.

The problem

The spreadsheet is the process. That's the problem.

Two opposite failures, equally expensive. Either the critical process is still an inbox and a spreadsheet, costing days of cycle time nobody measures - or a well-meaning colleague built the automation on a personal account, it quietly became load-bearing, and then they left.

Process throughput

The left column is what a manual queue actually looks like: it refills faster than it is worked, so the backlog is structural rather than a bad week. The right column is the same work flowing through routing, approval and logging without anyone needing to be at their desk.

The mistake: automating without governance, or not automating at all

Two failure modes, equally common. Either critical processes stay manual - approvals over email, data re-keyed between systems - or well-meaning staff build hundreds of ungoverned apps and flows on personal accounts, which quietly become production systems nobody can support when that person leaves.

What it costs

Cycle time measured in days because a request is sitting in an inbox. Errors from re-keying the same data three times. And a shadow estate of business-critical automations with no owner, no environment strategy, and no data loss prevention.

70%

reduction in vendor onboarding time for a national retailer

Before

Email approvals, re-keyed data

  • Spreadsheets
  • Email approvals
  • Shadow apps
  • Manual re-keying

After

Governed, automated, owned

  • Managed environments
  • Automated flow
  • DLP policy
  • System integration

Our approach

What we do differently

We automate the processes with real cycle-time cost, and we put an environment and governance model underneath so citizen development becomes an asset rather than a liability.

What good looks like

A national retailer's vendor onboarding ran on spreadsheets and email approvals across 45 regional teams. We rebuilt it on Power Apps and Power Automate against their ERP: onboarding time fell 70% and manual data entry errors in purchasing were eliminated.

  1. 1Find the processes where automation actually pays - measured in cycle time and error rate
  2. 2Establish environments, DLP policies, and an ALM path before scaling delivery
  3. 3Build the apps and flows, integrated with the systems of record
  4. 4Bring existing shadow automations under support or retire them deliberately
  5. 5Enable your team to build safely inside the guardrails

In depth

The detail behind the summary

Expand any chapter for the full reasoning - the failure modes we see most, why they happen, and what we do about them.

Finding the processes where automation actually pays

Not every manual process is worth automating, and building the ones that are not is how automation programmes lose their sponsor. The discipline is in selection, and the selection criteria are more specific than volume.

The processes that repay automation share a shape: they run often, they follow rules that can be written down, they involve waiting on a human who is not adding judgement, and they re-key data that already exists in a system of record. Vendor onboarding, access requests, expense approval, new-starter provisioning, invoice matching, field data capture - the same categories recur across industries because the underlying shape is the same.

The measure that matters is cycle time, not effort. A process that consumes ten minutes of someone's attention but sits in an inbox for four days is costing you four days. Automating it does not save ten minutes; it removes four days from a chain that something else was waiting on. That is where the return is, and it is invisible if you only measure headcount effort.

Error rate is the second measure. Every point at which data is typed from one system into another is a place where errors originate, and the cost of a purchasing error is rarely the correction - it is the downstream reconciliation, the supplier relationship, and the audit finding. Removing re-keying removes a whole class of failure rather than reducing its frequency.

How we prioritise

Cycle time multiplied by frequency, divided by build complexity. It is crude, and it consistently beats prioritising by whoever asked most recently.

The shadow estate, and why it exists

In almost every organisation running Power Platform without governance, there is an inventory nobody has: hundreds of apps and flows built by business users on individual accounts, some trivial, a handful genuinely load-bearing. Discovering this is usually uncomfortable, and it is worth being clear that it is not a failure of the people who built them.

They built them because a real business problem existed, IT had a backlog measured in quarters, and the platform made it possible. That is the intended outcome of low-code - the failure is architectural, not individual. What was missing was an environment strategy that gave them somewhere safe to build.

The risks are concrete. Flows running under a personal connection that stops when the account is disabled. Business data moving between services with no data loss prevention policy in the path. No source control, so there is no way to see what changed or to revert it. No test environment, so changes are made in production by definition. And no support model, so when it breaks the only person who understands it may no longer work there.

The remediation is not to ban it - that simply pushes it further out of sight. It is to inventory what exists, identify the genuinely business-critical subset, migrate those into managed environments with proper ownership and service accounts, and retire the rest on a communicated schedule. Then give people a governed place to keep building, because the demand that created the shadow estate has not gone away.

Governance that enables rather than blocks

Environment strategy is the foundation and it is usually the thing that was skipped. At minimum you need separation between where people experiment, where things are tested, and where the business depends on them - with different rules and different permissions in each. Without that separation, every governance control has to be set to production strictness everywhere, which makes experimentation impossible and drives people back to shadow building.

Data loss prevention policies define which connectors can be used together. This matters more than it sounds: the risk in low-code is rarely a single connector, it is the combination - a connector reading from your CRM in the same flow as one writing to a personal cloud storage account. DLP policies are what stop that combination existing, and they need to be designed per environment rather than applied uniformly.

Application lifecycle management means solutions, source control, and a deployment path from development through test to production. Low-code does not exempt you from this. A flow that approves payments deserves the same change discipline as any other system that approves payments, and the platform supports it - it simply has to be set up.

Done well, this makes citizen development an asset. People build inside guardrails, the critical things are identified and supported, and IT spends its time on the hard integrations rather than policing. Done badly - or not at all - you get the shadow estate back, and the second cleanup is harder than the first because trust has been spent.

Where low-code stops

Complex transactional logic, high-volume real-time processing, and anything with intricate state management have outgrown it. We will say so plainly rather than building something that technically works and becomes unmaintainable.

Copilot Studio and where conversational automation fits

Conversational agents fit a narrow and genuinely valuable slot: high-volume, well-bounded questions where the answer exists in documentation or a system, and where the current cost is a person answering the same thing repeatedly. Internal IT and HR support are the obvious cases, and they work.

They fit badly where the question is open-ended, where the consequence of a confidently wrong answer is significant, or where the underlying information is inconsistent. An agent grounded on contradictory documentation will answer contradictorily and with complete confidence, which is worse than no agent because it carries institutional authority.

The governance requirements are the same as anything else touching business data, and are frequently underestimated because the interface looks casual. Access to grounding data must inherit from your identity model rather than being granted to the agent broadly. Conversations and outputs need logging. There must be a defined escalation path to a human, and it must be easy to reach rather than buried.

Our position is that this is worth doing where the bounded case exists and worth declining where it does not. The failure mode we see most is an agent deployed with enthusiasm across an ambiguous domain, producing enough wrong answers in the first fortnight that people stop using it - after which the effort to rebuild trust exceeds the effort of the original build.

What you actually get

Concrete deliverables, not a statement of intent. Each one is something that exists at the end of the engagement and that your team owns afterwards.

Process discovery and prioritisation

Candidate processes measured on cycle time, frequency and error rate, ranked against build complexity, so the first delivery is the one with the clearest return rather than the loudest sponsor.

Environment and DLP architecture

Development, test and production separation with connector policies designed per environment, so governance constrains risk without making experimentation impossible.

Application lifecycle path

Solution packaging, source control and a deployment pipeline from development to production, so low-code changes get the same review discipline as any other production change.

Built apps and automations

The prioritised processes delivered on Power Apps and Power Automate, integrated with your systems of record rather than sitting alongside them as another data island.

Shadow estate remediation plan

An inventory of existing apps and flows, identification of the business-critical subset, migration of those into managed environments, and a communicated retirement schedule for the rest.

Maker enablement and guardrails

Your own team equipped to build safely inside the environment model, with the patterns, templates and review process that keep new work supportable.

When this isn't the right engagement

  • If the requirement involves complex transactional logic or high-volume real-time processing, it has outgrown low-code and we will recommend custom development instead.
  • If there is no willingness to establish environment separation and DLP policy, we can still build, but the shadow estate problem will return and we would rather you knew that before starting.
  • If the underlying process is broken rather than manual, automating it makes a bad process faster - process redesign has to come first and we will say so.

Questions we get asked

Is low-code robust enough for a core process?
For workflow, approvals, and data capture, yes - given proper environment strategy, source control, and support. We'll say plainly when a requirement has outgrown low-code and warrants custom development.
We already have hundreds of ungoverned flows. Now what?
We inventory them, identify which are business-critical, and bring those into managed environments with proper ownership. The rest get retired on a schedule rather than all at once.
Where does Copilot Studio fit?
It's a strong fit for high-volume, well-bounded internal questions. It needs the same governance as anything else touching business data - which is exactly the model we put in place.
