Development Stages

EMR/EHR CRM Application Development Stages

Research & Planning

  • Identify target users (doctors, nurses, admins, patients) and gather clinical, business, and system requirements.
  • Ensure regulatory compliance (HIPAA, FDA, GDPR, local laws).
  • Define scope, goals, and key features of the application.

System Design

UX/UI Design

Architecture Planning

Security Design

UX/UI Design

  • Create wireframes and prototypes
  • Design user flows.

Architecture Planning

  • Decide on the system architecture: monolithic/microservices, cloud/on-premise.
  • Choose the tech stack and plan the infrastructure.
  • Design database schema (relational and/or NoSQL).
  • Implement access control mechanisms: Role-Based Access Control or Attribute-Based Access Control.
  • Plan third-party integrations (laboratories, imaging systems, insurance platforms).

Security Design

  • Implement secure authentication (OAuth2, JWT).
  • Apply encryption for data at rest and in transit.
  • Set up audit logs and security event monitoring.

Proposal

Prepare a formal project proposal including:

Estimated scope of work/WBS

Business justification

Timeline and budget estimates

Environments Configuration

  • Define required environments: Development, Staging, QA, Production.
  • Set up infrastructure:
    • Cloud services (e.g., AWS, Azure, GCP)
    • Containers and orchestration (Docker, Kubernetes)
    • Secrets management
  • Set up monitoring and logging.

Pipelines (CI/CD)

Create automated pipelines:

Build, Test, and Deploy stages

Rollback and failover strategies

Deployment to test/staging environments

Automated linting, unit tests, and code quality checks

Development

Implementation

  • User Authentication and Role Management
  • Patient and Provider Dashboards
  • Electronic Medical Records (EMR/EHR)
  • Appointment Scheduling
  • CRM Features (reminders, segmentation, messaging)
  • Reporting and Analytics

Integration

  • HL7/FHIR APIs
  • DICOM/PACS
  • ICD-10/SNOMED
  • e-Prescription and lab systems

Quality Assurance

  • Manual and automated functional testing.
  • Unit, integration, and end-to-end testing.
  • Security testing (XSS, CSRF, SQL injection, etc.).
  • Performance and load testing.
  • User Acceptance Testing (UAT) with healthcare staff.

Project Management

  • Select methodology: Agile (Scrum/Kanban) or Waterfall.
  • Conduct daily stand-ups, sprint planning, retrospectives.
  • Use tools like Jira, Trello, or Azure DevOps.
  • Track progress with burndown charts, velocity metrics.

Deployment

Run CI/CD pipelines

Implement regular backups, uptime monitoring, and incident alerting.

Perform security audits and enable encryption across all services.

Maintenance and Scaling (optional)

Create automated pipelines:

Provide ongoing technical support and updates.

Collect feedback from users for continuous improvement.

Add new features based on user needs and regulatory changes.

Scale infrastructure to support more users, data, and integrations (e.g., mobile apps, telehealth modules).
