Transcript

  • 1. Bite sized training sessions: Scope of the Business Analyst Role
  • 2. Objectives • Review the scope of the BA role • Make a case for the importance of the BA role • Discuss whether a BA really is a BA… • Think about the ―analyst‖ part the BA title
  • 3. Putting the Business Analyst in context Owner/sponsor “I want it all I want it now I want it for free” Solutions developers “Given all the other projects we are already doing for you, the best we can do is a bit, in 6 months and it will of course cost a bit” Subject Matter Experts/Users “We must have this - and soon! - or our business will fail” BUSINESS ANALYST Programme/Project Manager “The sponsor will get it all, now and for free”
  • 4. Sponsor: We’re going to the moon! Project Manager: ok, we have to plan…first off, SME’s, what do you need? SME: We’ll need a spaceship and spacesuits! Business Analysts: Do we need anything else? Business Analysts: to answer your question I need to know… Why are we going to the moon? (Problem analysis) How will we know it was a worthwhile trip? (Objectives analysis) Therefore - what will we need to ensure it is worthwhile? (Requirements analysis) Developer: So we need to develop solutions for the following requirements…
  • 5. An example of rocket science...? Mars Climate Orbiter went in to orbit at 57km above Mars instead of 150km. It was completely destroyed. Cause: some navigation calculations performed in Imperial units (pound- seconds) and some in metric units (newton- seconds). Most project failures are due to incomplete/inaccurate requirements
  • 6. What do you think are the other main causes of project failure? Discussion
  • 7. The Standish Group “Chaos Report” (1994) The landmark study of project failure covering 365 executive managers and 8,380 applications in all major industry segments including: banking, retail and wholesale. Some of the contents of this slide were taken from www.it-cortex.com Why Projects Fail

  • 9. How can BAs mitigate the main risks for project failure? Discussion
  • 10. Relative cost of correcting error Barry Boehm Cost of analysis errors The cost of correcting analysis errors rises almost exponentially the longer they remain undetected.
  • 11. • 40-56% of bugs can be traced to requirement errors • Finding and fixing requirement errors consumes 70-85% of project rework costs • The average project exceeds its planned time schedule by 120% • 52.7% of projects will cost 189% of their original estimate • Only 16.2% of projects will be completed on time & on budget • 30% of projects are cancelled before completion. How much poor analysis £costs
  • 12. What do you think a business analyst does? Should PMs do what BAs do and vice- versa? Discussion

  • 15. Definition of terms for “Business Analysis” Business: why ―Business‖? …should it be Change Requirements??? Analysis: “the process of breaking a concept down into more simple parts, so that its logical structure is displayed” (OED) a : examination of a complex, its elements, and their relations b : a statement of such an analysis (Merriam Webster)
  • 16. Inductive VS Deductive Analysis • Induction: – a method of reasoning from a part to a whole, from particulars to generals, or from the individual to the universal. – Example: whenever I let go of a hammer, it falls to the ground. Therefore, every time I let go of a hammer it will fall to the ground. • Deduction: – a rigorous proof, or derivation, of one statement (the conclusion) from one or more statements (the premises)— i.e., a chain of statements, each of which is either a premise or a consequence of a statement occurring earlier in the proof. – Example: All fairies are pink. Tinkerbelle is a fairy. Therefore, Tinkerbelle is pink. • Which is better? That’s elementary, Watson.
  • 17. …and there’s more the BA needs to be thinking about… • Argumentation theory – how to discover the truth. • Philosophy – what is ―truth‖ in a business context and how to do we prove it? • Rhetoric – persuasion and/or enquiry? • Opinions – they matter but are only one tool – not the only tool! • Communication theories – how to best communicate what to who? …BAs are the analytical engine of a project…no-one else is accountable for doing it…we better do it well!
