REVEAL

REVEAL® is a requirements engineering method that helps projects to deliver the right systems for the right price, on time. Why is requirements engineering important?
  • 48% of the sources of project failure are requirements problems.
  • 41% of system errors are introduced during the requirements phase.
  • It costs 50 times more to fix a requirements error during acceptance testing than during the requirements phase.

REVEAL® is designed to attack the root causes of project failure by getting the requirements right at the start, and then managing the evolution of the requirements through the project.

What is different about REVEAL®?

REVEAL® is unique because it:
  • Focuses on the underlying requirements by first understanding what an organisation must achieve, before addressing what a system must do.
  • Actively identifies and resolves requirements conflict.
  • Recognises and incorporates requirements change management.
  • Supports a flexible choice of tools and notations.

The key elements of REVEAL®

  • Practical, well-tried techniques for producing precise, unambiguous requirements documents.
  • Soft skills, for dealing with the human stakeholders, individually and in groups.
  • Underlying engineering process, for bringing it all together.

REVEAL® has been applied successfully to:
  • Software systems development (including rapid application development).
  • Engineering projects (large scale, with a combination of mechanical, electrical, computer and people elements).
  • Process design.
  • Product strategy (developing and gaining agreement for future direction for manufactured products).

How we deliver REVEAL® to you?

  • Capability delivery. Praxis has a number of REVEAL® practitioners who can elicit, document and manage your requirements for you.
  • Capability enhancement. Praxis REVEAL® practitioners can work alongside your team to provide training and mentoring, and design and tailor your requirements processes and tools, building a lasting, effective requirements engineering capability.
  • REVEAL® training. Praxis runs open four-day REVEAL® training courses, or you may prefer a training programme tailored to your organisation’s specific needs. Praxis has trained over 400 engineers in REVEAL®.

Challenge

To deliver a significant reduction in downstream costs from requirements changes by implementing formal requirements engineering and management to a team of 100 engineers.

Engagement and approach

Praxis designed a long term "Capability Enhancement" programme.

An intensive initial stage provided formal training, supported by embedding of Praxis staff to support a rapid initial return.

Later stages involved regular debrief meetings and specific advice, with eventual completion of engagement with capability enhanced to client satisfaction.

Outcome

The client’s objectives were met, with full adoption of REVEAL® and a self sustaining requirements engineering capability.
