Systems Development Lifecycle Process

Introduction

RosettaHealth’s Systems Development Lifecycle Process (SDLC) uses a multi-phase approach based on industry standard Agile practices with additional processes used to encompass the unique nature of the RosettaHealth system. Each phase consists of a number of activities and deliverables.

Planning Phase

Purpose: Identify and prioritize the different work activities that are needed by the RosettaHealth system/product

Activities:

• Review work activities that are needed by HealthBus (enhancements, defects, operational actions, new features).

  • Define/revise the product planning tracker with task

  • Derive security requirements for any new features or functionality that has potential security implications

  • Evaluate security and compliance guidance for requirements

  • Assign technical team resources to each task.

Deliverable:

• Update to project planning tracker

Work Phase

Purpose: Perform the tasks necessary to build/implement/execute the tasks defined in the previous phase

Activities: Note that these activities are executed in a continuous cycle for each work item.

• Define/Design the flow of data within the solution including any dependent or depending systems.

• Analyze design against known security requirements. Specifically any components that touch PHI must be analyzed for:

  • Improper delivery of messages. 

  • Are messages delivered to the intended recipient

  • Improper access of messages. 

  • Can messages only be accessed by authorized users

  • Proper encryption of PHI.

  • All messages or other data must be encrypted in transit and at rest. 

  • Vulnerability of publically exposed interfaces. 

  • Are any public interfaces vulnerable to any recognized attack vectors. 

  • Develop testing tools to validate security requirements mentioned above.

• Implement: perform the necessary actions to create a Candidate Item

• Review: review of the implementation details by the technical team

• Test: develop, execute and document the testing mechanisms appropriate to the work item. Testing may include one or more of the following

  • Repeatable functional regression tests

  • Performance testing if applicable

  • Security testing for any identified security requirements

  • Third-Party system of systems testing

• DevOps Integration

  • Build and Deploy mechanisms appropriate for the Candidate item.

  • Define and verify monitoring integration for he Candidate Item

Deliverable:

• Candidate Item

• Test Cases

• Technical Support Information

Production Deployment and Operations Phase

Purpose:ensure that the Candidate Item is ready to be introduced and supported in the RosettaHealth production environment

Activities:

• Execute Production Deployment activities associated with the candidate time.

• Update associated FreshDesk ticket.
