Dynamics D365 Development

Extending Dynamics 365: Safe Development

Organisations turn to Dynamics 365 to unify operations. When standard configuration limits growth, bespoke development is necessary, but must be architected for long-term operational resilience and maintainability.

Operational Intelligence

Maintainability risks and technical debt patterns

Unmanaged custom development in Dynamics 365 can quickly degrade system stability and operational efficiency. We identify and remediate these patterns to secure long-term system health.

Over-customisation vs. Configuration

Symptoms

  • Minor functional changes require significant code
  • System upgrades become highly complex and costly
  • New features are slow to implement
  • Unnecessary custom entities or fields

Root Causes

  • Lack of initial configuration review
  • Developer preference for code over configuration
  • Inadequate understanding of platform capabilities
  • Insufficient requirements analysis
D365 CoreDataversePower Apps

Impact: Increased total cost of ownership, reduced agility, and heightened risk during platform updates. Retailers become locked into brittle, custom solutions that inhibit innovation.

Cogent Approach: We conduct thorough reviews of existing customisations against platform best practices and guide teams to use standard functionalities. This reduces code footprint and improves upgrade resilience.

Untested & Undocumented Code

Symptoms

  • Frequent unexpected behaviours post-deployment
  • Difficult to debug or extend existing functionality
  • New developers struggle to understand the codebase
  • Integration failures due to unhandled edge cases

Root Causes

  • Absence of a robust testing framework
  • Lack of code review processes
  • Time pressure prioritising delivery over quality
  • Insufficient technical documentation
D365 environmentsAzure DevOpsUnit Test Frameworks

Impact: Increased operational risk, more support tickets, and reduced developer productivity due to time spent re-learning and fixing issues. This often breaks first.

Cogent Approach: We implement structured testing methodologies (unit, integration, UAT), establish code review guidelines, and enforce documentation standards to ensure maintainable, reliable code.

Dependency on Single Developer / Vendor

Symptoms

  • Knowledge silos within the team
  • Delays when the primary expert is unavailable
  • Reluctance or inability to change outsourced vendors
  • Lack of cross-training or knowledge sharing

Root Causes

  • Poor knowledge transfer processes
  • Lack of internal technical leadership
  • Vendor lock-in strategies without due diligence
  • Insufficient investment in internal training
D365Azure ADSource Control

Impact: Significant operational vulnerability if key personnel leave or vendor relationships sour. The symptom hides the cause.

Cogent Approach: We implement knowledge transfer programmes, recommend distributed ownership models, and help establish internal technical governance to mitigate single-point-of-failure risks.

Unmanaged Integration Points

Symptoms

  • Data inconsistencies between connected systems
  • Manual intervention required for data synchronisation
  • Performance degradation during data exchanges
  • Lack of visibility into integration failures

Root Causes

  • Ad-hoc integration development
  • Absence of monitoring or alerting for integrations
  • Failure to account for data volumes and frequency
  • Bypassing iPaaS layers for 'quick' fixes
D365 DataversePatchworksData Export Service

Impact: Corrupted decision-making, increased operational cost for manual reconciliation, and a poor customer experience due to outdated or incorrect data.

Cogent Approach: We design robust integration architectures incorporating monitoring, error handling, and appropriate iPaaS usage (e.g. Patchworks) to ensure reliable data flow and system synchronisation.

Future-Ready Operations

Preparing Dynamics 365 for the next scale / phase relevant to development

Future-proofing Dynamics 365 development involves architecting for evolving business needs and technological shifts. This means adopting modular design principles, leveraging Azure services, and standardising development practices.

We help organisations move beyond reactive development to proactive architectural planning. This ensures that new customisations and features can be built, deployed, and maintained with minimal operational disruption and maximum long-term value.

The goal is an extensible Dynamics 365 environment that supports growth without legacy constraints. This requires careful consideration of data models, integration patterns, and continuous delivery pipelines.

Knowledge Base

Frequently Asked Questions

Technical & Development Focus
When should we consider custom development for Dynamics 365?
Custom development is typically necessary when specific business processes cannot be met through standard configuration or existing third-party solutions. It should always be a last resort, after thorough analysis of native capabilities and careful consideration of long-term maintainability.
How do you ensure customisations are maintainable?
We enforce strict coding standards, thorough documentation, comprehensive unit and integration testing, and architectural reviews. Our approach prioritises modular design and minimises direct modifications to core Dynamics 365 components, making upgrades smoother.
What is your approach to technical debt?
We proactively identify and document technical debt during audits and new development, creating a clear remediation roadmap. This includes refactoring, deprecating outdated customisations, and ensuring new development adheres to best practices to prevent future accumulation.
Process & Governance
How do you manage the development lifecycle?
We advocate for an agile development approach, with continuous integration (CI) and continuous delivery (CD) practices. This involves regular sprint cycles, frequent communication, automated testing, and phased deployments to minimise risk and deliver value iteratively.
How do you work with existing in-house development teams?
We collaborate closely with your internal teams, providing mentorship, knowledge transfer, and joint development efforts. Our goal is to augment your capabilities, share best practices, and establish a framework for sustainable internal development.
