Iterative / Incremental

Drive Innovation through Flexibility with PTC Integrity


Iterative and Incremental development methodologies such as UP (Unified Process), RUP (Rational Unified Process) or Spiral Development are successful because they offer some of the advantages of pure Agile while providing more structure similar to traditional processes. They promote shorter development cycles, frequent releases and more involvement from users to reduce risk, improve quality and improve the organization's ability to adapt to changing requirements. They also offer flexibility in both process and formality, enabling organizations to adapt processes to the relevant standards and regulations and scale them to large development efforts.

These benefits, however, can be difficult to achieve using traditional siloed tooling. Rapid cycles or iterations demand streamlined activities, cross-discipline teams and improved communication. This creates unique demands from their development lifecycle management tools:

 
Challenge PTC Integrity Capability
Moving development to shorter iterations requires teams to maximize efficiency and reduce overhead. Relying on a collection of tools and manual documentation results in redundancies and inefficiencies that reduce team productivity and velocity.
  • True artifact management. Artifacts are written once and linked to, eliminating redundant replication of documents or files
  • Advanced reuse of all lifecycle assets including features, requirements, code, test cases, test results, enabling a 'living architecture' that can be leveraged in later iterations
Iterative development demands cross-discipline teams, including stakeholders, to maximize communication. Traditional domain specific tools that encourage silos are not compatible with this philosophy, and undermine the effectiveness of this method.
  • A single source of truth for all development, dramatically improving team collaboration and communication efficiency
  • Multiple domain specific views and filtering of data enabling teams to focus on their activities
  • Immediate propagation of changes upstream AND downstream speeding reaction to change
A collection of discipline specific tools and manual documentation undermines the flexibility of iterative development methodologies. Tools must be capable of being adapted quickly and easily
  • Out-of-the box support for Agile, iterative, and waterfall processes
  • Configurable process automation via PTC Integrity's graphical workflow designer
In the rapid turnaround of Iterative development, management needs to immediately identify and react to issues and impediments. This demands real-time visibility across the project
  • Comprehensive real-time metrics dashboards identify bottlenecks
  • End-to-end automated data collection results in reliable project metrics
  • Traceability across all artifacts and disciplines gives management the ability to assess change impact in real-time
Iterative development methodologies like RUP emphasize the utilization of Use Cases to drive development.  Traditional tools may be able to capture use cases, but are unable to effectively manage the flowdown of use cases into design, test and code as well as manage frequent change impacts across the lifecycle
  • PTC Integrity allows teams to capture and structure use cases in a variety of ways providing flexibility while giving the team specific guidance and consistency.
  • Traceability to downstream artifacts is a strength with PTC Integrity’s single data model.
Managing risk as relating risks to development artifacts is also common in iterative development methods.  Most traditional tools do not allow for integrated risk management and therefore lack the traceability and reporting capabilities to efficiently manage risk in the context of a fast paced iterative process
  • PTC Integrity offers integrated risk management that allows instant reporting and real-time visibility into risks and mitigations.
Compliance to development and engineering standards and industry regulations can decrease efficiency and push out cycle times, especially when relying on manual documentation or federated tools
  • Enforceable process control for regulated entities or practices without impeding productivity or velocity
  • Automated change and history tracking  for complete traceability
  • Out-of-the-box solutions for industry standards such as ISO 26262, ISO 14971 and DO-178c
