We all know that you can really only manage what you measure. But most IT Professionals cannot articulate most project and product qualities and values quantitatively at all. Most people simply use nice words (better usability, higher security) or even worse, they specify the technology (iPhone app, encryption) rather than the desired quality result.

It is always possible to usefully quantify, and then measure, all qualities, and all critical stakeholder values. We will teach you how.

The quality quantification skill is the basis for your ability to carry out most all useful IT development and management processes, such as communication, requirements, architecture, project management, contracting, quality assurance, decision making, supplier, prioritization, risk management and product selection.

It is the key to avoiding project failure, budget and deadline overrun. You have to manage essential qualities: and to do that you must quantify them.

The course will mainly be lectures, backed up by simple exercises (quantify X, set a minimum level).

The student will be given a digital library of technical and management literature to allow them to study more.

If you would like a sample of the depth and practicality of the method, you can look at tinyurl.com/Valueplanning, a book currently being written by Tom Gilb.

  • How to analyze any incoming stream of needs, wishes, requirements, objectives - however vague and unstructured
  • How and why to classify incoming wishes
  • Levels of Perception: Stakeholder level, System/Product level
  • Identification of your top level of values and quality requirements
  • Prioritization: aspects and process
  • The Quantification Process
  • Quantification Specification Rules (Standards for written specification): best Practices for specification
  • Quality Control of Written Specification: Measuring levels of defects
  • The use of ‘Ambition Level’ to scope and initiate the process of quantification
  • Resolving Conflicting Opinions: The Ambiguity Test
  • Knowing When a Quality should be decomposed into sub-qualities. Complex and Elementary Qualities
  • Quality Patterns
  • Tailoring the Patterns
  • The Scale of measure: Basics
  • Scale Parameters: making a general and reusable scale.
  • Cross referencing initial inputs to the quantification process
  • Getting stakeholders to understand and agree to quantifications
  • Templates for specification
  • Benchmarks: Past, Trend, Record, Ideal
  • [Qualifiers]: when, where, If? Conditions for a level of quality
