Idealized D365 Implementation — Project Gantt Chart

What happens

Stand up the project team, confirm executive sponsorship, define roles and responsibilities (RACI), and establish the organizational structure that will own the solution. The team aligns on vision, scope, and ways of working before detailed work begins.

Key stakeholders

Best practices

• Secure visible, active executive sponsorship early.
• Define a clear RACI and decision rights up front.
• Align partner and customer teams as one team.
• Agree escalation and communication paths before build.

What happens

Articulate why you're implementing D365 and the value or digital transformation it should deliver. Choose the deployment approach (phased vs. big-bang, single vs. multi-app) and set guiding principles such as "keep it standard" and cloud-first agility.

Key stakeholders

Best practices

• Tie the strategy to measurable business outcomes.
• Favor out-of-the-box capability; minimize customization.
• Claim value early rather than running a long waterfall.
• Stay aligned to the Microsoft product roadmap.

What happens

Elicit, document, and validate functional and non-functional requirements through workshops, then prioritize them (e.g., MoSCoW) and trace them back to the business processes they support.

Key stakeholders

Best practices

• Anchor requirements to end-to-end business processes.
• Prioritize ruthlessly — not everything is "must have."
• Capture non-functional needs (volume, performance, compliance).
• Maintain a single, traceable backlog.

What happens

Document current-state ("as-is") processes and design future-state ("to-be") processes aligned to standard D365 capabilities, using Microsoft's end-to-end business process catalog as the reference model.

Key stakeholders

Best practices

• Start from the standard process catalog, then adapt.
• Design to standard before considering customization.
• Name an accountable owner for each process.
• Log every gap as a candidate backlog item.

What happens

Map requirements to D365 capabilities, identify gaps, and decide configure vs. extend vs. integrate for each one. Produces the conceptual solution that frames scope and effort.

Key stakeholders

Best practices

• Resolve gaps with configuration first.
• Document the rationale for every customization.
• Flag high-risk gaps early for deeper review.
• Validate feasibility with prototypes or spikes.

What happens

Plan the set of environments (dev, test, UAT, training, production), their topology, data refresh and retention policies, and how code and configuration promote between them.

Key stakeholders

Best practices

• Define each environment and its purpose early.
• Automate provisioning wherever possible.
• Tightly control who can deploy to production.
• Keep production isolated and well governed.

What happens

Break the solution into in-scope workstreams and define the delivery plan (sprints / milestones), dependencies, and resourcing. The plan is refined as the solution blueprint firms up.

Key stakeholders

Best practices

• Plan in iterations, not one long waterfall.
• Make cross-workstream dependencies explicit.
• Build in time for Success by Design reviews and testing.
• Treat the plan as living — revisit it continuously.

What happens

Establish governance bodies (steering committee, change-control board), meeting cadence, decision rights, risk and issue management, and status reporting for the life of the project.

Key stakeholders

Best practices

• Meet on a predictable cadence.
• Keep one source of truth for risks, issues, and decisions.
• Empower the steering committee to make scope/budget calls.
• Feed Success by Design findings into governance.

What happens

Consolidate the solution design — data model, security, integration, ALM, testing approach, environment plan — into a blueprint that becomes the baseline artifact for the mandatory Solution Blueprint Review.

Key stakeholders

Best practices

• Make the blueprint complete enough to surface real risks.
• Align the design to the product roadmap.
• Run the Solution Blueprint Review before heavy build.
• Keep the blueprint a living document.

What happens

Stand up the initial development and test environments per the environment strategy, and wire up ALM connections and role-based access so the build can begin.

Key stakeholders

Best practices

• Provision early to unblock the build team.
• Apply least-privilege access from the start.
• Baseline configuration as code.
• Document the environment topology.

What it checks

The first and mandatory Success by Design review. It examines the high-level solution design, architecture, scope, and the defined workstreams to confirm the project is following recommended patterns — before the build goes too far. Its findings are what trigger the deeper, topic-specific Implementation Reviews.

Who's involved

Outputs & outcomes

• Findings classified as Assertions, Risks, or Issues, each matched to known patterns.
• Recommendations and actions to mitigate risk.
• A list of follow-on Implementation Reviews to schedule.

What happens

Establish application lifecycle management — source control, solution and branching strategy, automated build and deployment pipelines, and release management — so changes flow safely from dev to production.

Key stakeholders

Best practices

• Use managed solutions and source control from day one.
• Automate builds and deployments.
• Gate releases between dev / test / prod.
• Never make manual changes directly in production.

What happens

Design the Dataverse / finance & operations data model (tables, relationships) and the security model (roles, business units, field-level security) so they support the processes, reporting, and compliance requirements.

Key stakeholders

Best practices

• Design security around roles and least privilege.
• Model data to support reporting and integration.
• Validate the model against volume and performance.
• Document the data and security design.

What happens

Iteratively configure standard D365 capabilities to meet requirements across functional areas, demonstrating working increments to the business at the end of each sprint.

Key stakeholders

Best practices

• Configure before customizing.
• Demo every sprint to gather feedback early.
• Keep configuration documented and in source control.
• Work from a prioritized backlog.

What happens

Key stakeholders

Best practices

• Extend, don't over-customize.
• Follow supported extension patterns only.
• Peer-review code and cover it with automated tests.
• Document every custom component and its justification.

What happens

Design and build integrations with other systems (legacy, third-party, other Microsoft cloud), choosing patterns — real-time vs. batch, APIs, events — and handling throughput and error recovery.

Key stakeholders

Best practices

• Match the pattern to the volume and latency needs.
• Design for resilience and idempotency.
• Plan carefully for high-volume legacy systems.
• Monitor and log every integration.

What happens

Key stakeholders

Best practices

• Start data profiling and cleansing early.
• Migrate only the data you actually need.
• Run multiple dry runs and reconcile results.
• Get business sign-off on migrated data quality.

What happens

Implement the designed security roles, business units, teams, and access controls in the solution, aligning them to the organizational structure and compliance requirements.

Key stakeholders

Best practices

• Implement least privilege throughout.
• Test roles with representative user personas.
• Honor segregation-of-duties requirements.

Key stakeholders

Best practices

• Define a reporting strategy up front.
• Separate operational from analytical workloads.
• Reuse a curated, governed data model.
• Validate every number with the business.

What it checks

Topic-specific deep dives that follow from the Solution Blueprint Review findings — covering the data model, security, integration, ALM, and testing strategy. They address identified risks while the build is still early enough to change course.

Who's involved

Outputs & outcomes

• Deeper findings and recommendations on the specific area under review.
• Mitigation actions fed back into the build and the risk log.
• Risks resolved before the solution build is too far along.

What happens

Execute end-to-end functional and integration test cycles against the built solution, logging defects and driving them to resolution before user acceptance testing.

Key stakeholders

Best practices

• Test end-to-end processes, not just individual features.
• Use representative data and scenarios.
• Automate regression testing where you can.
• Triage defects with clear severity and ownership.

What happens

Validate that the solution meets non-functional performance targets at expected scale — users, data volumes, and integrations. Leaving this out of scope is a well-known risk the Solution Blueprint Review specifically looks for.

Key stakeholders

Best practices

• Don't assume the cloud guarantees performance — test your customizations and integrations at scale.
• Model realistic peak load.
• Resolve bottlenecks before go-live.
• Keep performance testing in scope from the start.

Key stakeholders

Best practices

• Detail every task with an owner and a duration.
• Define go/no-go criteria and a rollback plan.
• Rehearse the runbook in mock go-lives.

Key stakeholders

Best practices

• Define support tiers and escalation before go-live.
• Staff hypercare adequately for fast response.
• Equip support with complete documentation.
• Plan the handover from project to support.

What happens

Execute one or more full rehearsals of the cutover runbook in a production-like environment to validate timing, steps, and overall readiness for the real cutover.

Key stakeholders

Best practices

• Rehearse the full runbook end to end.
• Time each step to confirm the cutover window.
• Fix gaps and re-rehearse as needed.

What it checks

The mandatory final review before go-live. It confirms the solution is built and tested, customer approvals are granted, information security reviews are complete, the cutover plan is defined with go/no-go criteria, mock go-lives are scheduled, the support model is ready, and the deployment runbook is complete with tasks, owners, durations, and dependencies.

Who's involved

Outputs & outcomes

• Identification of any remaining gaps or issues.
• A clear go / no-go recommendation.

Key stakeholders

Best practices

• Staff hypercare for rapid response.
• Triage and prioritize incidents transparently.
• Monitor adoption and performance closely.

Key stakeholders

Best practices

• Start change management at project kickoff.
• Build and nurture a champion network.
• Communicate the "why" repeatedly and clearly.
• Measure adoption and adjust your approach.

What happens
