Your Dynamics 365 HR project is live. People can log holidays, managers can approve requests in Teams, onboarding workflows are moving through Dataverse, and the project team has finally come up for air. That's usually the point where organisations make one of two mistakes.
They either declare success too early, or they avoid looking too closely because they already know a few rough edges will surface.
A proper post implementation review sits between those two extremes. It gives HR, IT, and operations a structured way to test whether the system is working in real life, not just in a demo script or go-live checklist. For UK mid-market firms, that matters even more when the project includes Dynamics 365, Power Platform, automated onboarding, document retention, and compliance controls such as UK Right to Work and GDPR.
Generic project guidance often treats a review as a short lessons-learned session. In practice, that's not enough for HR platforms. If your system touches employee records, identity checks, absence, expenses, training, or recruitment, the review needs to examine user adoption, operational fit, integration reliability, and compliance behaviour together. Otherwise, you can miss the exact problems that create workarounds, audit risk, and poor confidence in the platform.
Laying the Groundwork for a Successful Review
A review fails long before the workshop if nobody decides what it's for. In Dynamics 365 HR projects, the risk is obvious. HR wants to discuss process pain, IT wants to discuss support tickets, finance wants to discuss value, and managers want to discuss whether their teams are using the thing. If you don't set boundaries, the session turns into a general debrief and nothing gets resolved.
Start with scope. Review one implementation, one period, and one set of business outcomes. If you've rolled out Core HR, onboarding, leave management, and employee self-service at the same time, keep the review centred on what's been live long enough to judge properly.
Pick the right review window
Timing changes the quality of the evidence. Too early, and users haven't settled into the new process. Too late, and people forget what happened during training, cutover, and early support.
For project implementations, the best time to run a post implementation review in the UK is between 2 to 6 weeks after project completion, which allows the system to be in active use while keeping feedback fresh, according to MIGSO-PCUBED's post implementation review best practices.
That range works well for most Dynamics 365 and Power Platform HR deployments, but only if the live scope is stable. If data migration defects or access issues are still dominating support, delay the workshop slightly and collect evidence first. You need lived usage, not launch-day noise.
Define what success means before people start talking
Most review meetings drift because the team never agreed what they're measuring. Use a short review charter with four elements:
- Business outcomes: Has the system reduced manual HR administration, improved onboarding flow, or removed duplicate entry?
- Operational outcomes: Are approvals, alerts, and hand-offs working as intended across HR, managers, and employees?
- Technical outcomes: Are integrations, security roles, forms, and automations behaving consistently?
- Compliance outcomes: Are document retention rules, consent handling, and Right to Work steps operating correctly after go-live?
A well-structured Dynamics 365 implementation project plan makes this easier, because the original goals, dependencies, and ownership should already exist. If they don't, your review needs to rebuild that baseline before anyone can assess success accurately.
Practical rule: If the review objective can't fit on one page, the scope is too broad.
Bring the right people into the room
A strong review team isn't just senior stakeholders. It needs the people who see what the system looks like in daily use.
A useful mix usually includes:
| Role | What they contribute |
|---|---|
| HR lead | Process fit, policy alignment, user pain points |
| System owner | Configuration decisions, release history, backlog items |
| IT or platform lead | Security, integrations, support patterns |
| Front-line manager | Approval experience, workflow friction |
| End user representative | Self-service usability and training reality |
One more point matters. Assign a facilitator who can keep the conversation neutral. The review should test decisions, assumptions, and process design. It shouldn't become a defence of the project.
Defining KPIs and Collecting Mission-Critical Data
A post implementation review without hard evidence usually rewards the loudest opinion in the room. In HR system projects, that's dangerous, because low adoption might look like “resistance to change” when the underlying problem is poor mobile usability, weak role design, or a broken approval route.
The most reliable reviews use a balanced metric set. For UK enterprise software PIRs, expert specifications call for four dimensions: technical, operational, user-focused, and business impact. The same guidance also notes a common UK failure point: 40% of mid-market Dynamics 365 implementations fail their initial PIR due to unaddressed GDPR or UK Right to Work data retention gaps, as outlined in MyShyft's post implementation review guidance.
Technical KPIs that show whether the platform is stable
Start with the parts users notice first, then move to the parts they don't.
A sensible technical evidence pack includes:
- System reliability: Uptime patterns, failed flows, integration retries, and sync failures between Dataverse and connected services.
- Performance in real use: Slow forms, delayed approvals, poor mobile behaviour, and page load issues in common tasks such as leave requests or onboarding forms.
- Security and role behaviour: Access issues, over-permissioned roles, or users blocked from tasks they should complete.
For Dynamics 365 and Power Platform, I'd also inspect Power Automate runs, audit history, business rule behaviour, and exception handling around document uploads. Technical stability isn't only about whether the environment stayed online. It's about whether users can complete the process without asking HR for help.
Operational and user measures that reveal process truth
Operational review is where many teams finally discover whether they digitised a process or just moved the same friction into a new screen.
Look at:
- Recruitment and onboarding flow: Are forms completed in sequence, approvals happening on time, and documents reaching the correct record?
- Compliance completion: Are Right to Work tasks triggered and closed correctly? Are retention policies attached to the right record types?
- Training effectiveness: Which teams are self-sufficient, and which still rely on shared mailboxes or manual intervention?
User evidence should mix system usage with direct feedback. Completion rates matter, but so does confidence. If line managers keep emailing HR instead of using self-service, adoption is weak even if logins look healthy.
A practical way to pull this together is to compare system analytics with a focused HR KPI dashboard. That helps separate a training issue from a workflow issue, and a workflow issue from a configuration issue.
Metrics should answer one question clearly. Is the system making work easier, safer, and more consistent, or has it simply moved the effort somewhere else?
Business impact needs more than a budget line
At this stage, teams often become too vague. “The project went well” isn't useful. Neither is “users seem happier”.
Business impact should connect the implementation to outcomes the organisation cares about, such as reduced admin effort, clearer accountability, quicker document handling, improved reporting confidence, and better policy adherence. If your original business case included fewer manual onboarding steps, less paper handling, or stronger auditability, test those assumptions directly.
For HR leaders, one useful discipline is to compare intended value against where effort is still sitting. If HR administrators are still chasing managers for approvals, uploading duplicate files, or correcting bad starter data, your system may be live but it isn't yet optimised.
Running an Effective Post Implementation Review Workshop
The workshop is where good preparation either pays off or gets wasted. A poor session usually has one of two problems. It's either too polite to surface anything meaningful, or too chaotic to produce a usable outcome.
The first fix is structure. Send a short evidence pack in advance, ask for written comments before the meeting, and make it clear that the session is about process learning, not personal performance.
Use an agenda that starts with outcomes, not grievances
The strongest review workshops follow a simple flow:
- Restate the original implementation purpose
- Review the evidence
- Confirm what worked well
- Examine friction points and exceptions
- Identify root causes
- Agree actions, owners, and follow-up dates
This order matters. If you open with complaints, the room narrows too fast. If you start with intended outcomes and real evidence, the discussion stays grounded.
For organisations already using structured planning cycles, it can help to borrow ideas from effective OKR review cadences. The discipline is similar. You're checking progress against intended outcomes, not collecting unfiltered opinion.
Keep the conversation blameless and specific
When the system is new, people often explain problems in personal terms.
“Managers aren't engaging.”
“HR didn't explain it properly.”
“IT made it too complicated.”
Those statements rarely survive scrutiny. What usually sits underneath them is something more useful: a missing approval notification, unclear ownership, poor training by role, or a process that looked fine in a workshop but failed in real daily use.
Use prompts that force specificity:
- What exact step breaks down?
- Who experiences it first?
- Is the issue consistent or occasional?
- Did it begin at go-live or after a change?
- What evidence supports the point?
Ask people to describe the task, not the frustration. You'll get to the real issue faster.
Capture findings live
Don't wait until after the meeting to interpret everything from memory. Use a visible action log while the group is talking.
A simple format works well:
| Finding | Evidence | Root cause hypothesis | Owner |
|---|---|---|---|
| Managers bypass self-service | Email approvals still common | Notifications unclear on mobile | HR systems lead |
| Starter records incomplete | Missing fields in new hire process | Form design and training gap | Project owner |
Visible capture changes behaviour. It reduces repetition, keeps disagreements focused, and stops the workshop from wandering into abstract debate. It also helps participants see that the discussion is moving towards decisions, not just airing concerns.
Analysing Findings and Navigating Common Pitfalls
Once the workshop ends, the actual work starts. This is the point where many organisations produce a neat summary of comments and miss the actual diagnosis. A useful post implementation review doesn't stop at “users struggled” or “data quality was mixed”. It explains why.
For UK HR projects, that means separating symptom from source. Low adoption might be caused by awkward navigation, inconsistent master data, poor mobile design, weak training by role, or a business process that no longer matches operational reality. If you don't test those possibilities, you'll fix the wrong thing.
Look for patterns across systems, process, and people
I usually sort findings into three lenses:
| Lens | Typical signs | What to test |
|---|---|---|
| Technical | Errors, failed automations, missing updates | Configuration, integrations, permissions |
| Procedural | Rework, duplicate steps, manual workarounds | Process design, policy fit, hand-offs |
| Organisational | Low confidence, inconsistent use | Training, ownership, change readiness |
That split matters because the same issue can surface in several ways. A manager who avoids self-service might seem like an adoption problem. In practice, the root cause may be procedural because approvals arrive without enough context, or technical because the Teams notification isn't reliable.
This is also where migration decisions come back into view. Weak legacy mapping, duplicate employee records, and poor document indexing can undermine confidence for months after go-live. If that's part of your picture, revisit the assumptions behind your data migration strategy before changing anything else.
Unintended consequences are usually where the value sits
Good reviews expose what planning missed. That's one reason PIRs matter so much in compliance-heavy environments.
In one Public Sector Approach trial, a post-implementation review found that after a new system was introduced, the average number of reported breaches increased by 11% to 1,267 per quarter, according to the UK legislation PIR annex for the 2016 order. That kind of finding is exactly why HR and compliance teams shouldn't assume that a successful launch means safe operation.
For Dynamics 365 and Power Platform HR projects, the UK-specific blind spots are usually these:
- Retention controls weren't validated in live use: The policy existed, but real records didn't follow the intended lifecycle.
- Right to Work checks were configured but not operationally embedded: Tasks were created, but ownership and closure weren't clear.
- Satellite processes were ignored: The core workflow worked, but payroll inputs, document storage, or manager escalations still sat outside the design.
- User adoption was measured too shallowly: Logins looked fine, yet HR remained the manual fallback for key tasks.
A useful way to sharpen this analysis is to review examples of how organisations present business review findings. The format ideas in 8 quarterly business review examples can help teams turn scattered observations into a clearer narrative with priorities and decisions.
Surface symptoms are expensive. Root causes are fixable.
Prioritise by operational risk, not annoyance
Not every issue deserves equal urgency. Categorise findings by impact on compliance, employee experience, managerial workload, and platform reliability.
One practical ranking model is:
- Immediate action: Compliance gaps, broken automations, access issues, failed approvals
- Planned improvement: Training gaps, reporting tweaks, form redesign, workflow simplification
- Monitor: Minor usability friction, local workarounds with limited risk, low-frequency exceptions
That order keeps teams from spending weeks polishing screens while retention, access, or evidence trails remain unresolved.
Creating Your Action Plan for Continuous Optimisation
A post implementation review earns its value after the meeting, not during it. If the findings don't become named actions with dates and ownership, the review becomes expensive note-taking.
The strongest action plans are short, specific, and visible. They don't try to solve everything in one pass. They create an ordered backlog that improves the live service without destabilising it.
Turn findings into owned decisions
Each recommendation should answer five points:
- What needs to change
- Why it matters
- Who owns it
- When it will be reviewed
- How success will be judged
That sounds basic, but it's where many PIR reports fall apart. Teams write broad recommendations such as “improve training” or “optimise approvals”. Neither is actionable. “Redesign manager approval guidance for mobile users and test with one business unit” is actionable.
Here's a practical format:
| Action | Owner | Priority | Review point |
|---|---|---|---|
| Correct retention rules for leaver documents | Compliance lead | Immediate | Next governance meeting |
| Simplify starter form fields for managers | HR systems owner | Planned | After UAT of revision |
| Refresh manager self-service training | HR operations | Planned | Following next intake |
Separate quick wins from structural fixes
Not every issue needs a project. Some need configuration changes, some need policy clarification, and some need stronger operational discipline.
A sensible split looks like this:
- Quick wins: Notification wording, role guide updates, field labels, approval reminders
- Medium-term improvements: Form redesign, revised flows, dashboard changes, training by persona
- Strategic changes: Governance updates, process redesign, compliance model changes, roadmap decisions
This is also the point to test whether the new platform has created any hidden friction. UK government guidance on PIRs says reviews should capture “unintended effects” and assess “innovation impacts” to see if a measure has “locked-out innovation”, as set out in the UK government principles of best practice for post-implementation reviews. Mid-market firms should apply the same discipline to digital HR projects. If your new system standardised a process so tightly that managers now avoid it, that's a design problem, not user stubbornness.
Build the review into normal governance
The biggest mistake after a PIR is treating it as the end of the project. It should feed straight into service improvement, release planning, and HR governance.
Use a lightweight cadence:
- Monthly service review: Check progress on immediate fixes
- Quarterly optimisation review: Assess whether improvements delivered the expected operational change
- Future project planning: Reuse lessons in later Dynamics 365 and Power Platform rollouts
A strong PIR report should become a working document. It needs version control, clear status tracking, and enough detail that a new project lead can understand the issue without replaying the whole project.
Your Partner in HR Transformation
A post implementation review gives you something most go-live plans don't. Proof. Proof of where the platform is working, where users are finding friction, where compliance controls need tightening, and where the business case needs refining in the light of real usage.
That matters in the UK mid-market because HR systems rarely stand alone. They sit inside Microsoft 365 estates, connect to Outlook, Teams, SharePoint, Power BI, and Power Apps, and carry sensitive employee information across the entire hire-to-retire lifecycle. If the review is shallow, the risks stay hidden. If the review is structured, you get a practical route to better adoption, cleaner processes, and stronger control.
DynamicsHub.co.uk works with organisations that need more than a generic implementation partner. Experience HR transformation built around your business. Hubdrive's HR Management for Microsoft Dynamics 365 is the premier hire-to-retire solution, more powerful, more flexible, and more future-ready than Microsoft Dynamics 365 HR.
That's a significant advantage for organisations that need UK-specific HR capability, including Right to Work processes, GDPR-aligned retention, integrated employee records, recruitment, onboarding, absence, performance, expenses, and broader Power Platform extensibility inside their own Microsoft environment. The point isn't just to get live. It's to keep improving once you are.
A disciplined post implementation review is one of the best ways to protect that investment. It helps you move from “the system is deployed” to “the system is delivering”. There's a big difference between those two states, and most of the long-term value sits in the gap.
If your Dynamics 365 or Power Platform HR project is live and you're not fully confident it's performing as it should, now is the right time to review it properly.
