Write a good analysis training - odoo-ps/psbe-process GitHub Wiki

What’s a good analysis?

• WARNING : The perfect specification doesn’t exist!
• It’s impossible to spot all the details corner case
• Every developer has its own version of the perfect specification
• It’s completely normal, be gentle with people who wrote shitty specification but not with their specification
• This is not a reason to not make it seriously

Structure of the analysis

• Context

  • Practical information (DB, admin, Apps/Objects, etc.)
  • Sector
  • Project scope
  • Existing customizations
  • Platform (Saas or Odoo.sh or On Premise) : May change at the end of the process

• Business need

  • WHAT: Explain the problem to solve
  • WHY: Explain added value for the client
  • WHO: Indicate which profiles will be impacted

• Functional analysis

  • HOW at flow level
  • Scenario with the expected flow (TO BE)

• Technical analysis

  • HOW from the technical point of view
  • Estimation
  • Reliability

Reliability Definition

• The estimation will not be the real time spent
  • It depends on many factor we don’t know: code complexity, client, BA, developer, luck , ...
  • It gives you only the mean of the gauss distribution
• The reliability is an indicator for the standard deviation
  • Lower is the reliability bigger is the standard deviation

The LOWER is the reliability... ...the BIGGER is the standard deviation

We can only give a confidence interval
