Bite sized training sessions: Scope of the Business Analyst Role
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
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
Sponsor: Were going to the moon! Project Manager: ok, we have to plan…first off, SMEs, what do you need? SME: Well 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…
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
What do you think are the other main causes of project failure? Discussion
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 Why Projects Fail

How can BAs mitigate the main risks for project failure? Discussion
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.
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
What do you think a business analyst does? Should PMs do what BAs do and vice- versa? Discussion

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)
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? Thats elementary, Watson. »Definitions from Encyclopaedia Britannica 2008
…and theres 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!
