Transcript of 01 scope of the ba role
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 allI 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”
BUSINESSANALYST
Programme/Project Manager“The sponsor will get it all,
now and for free”
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…
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.

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?

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? That’s elementary, Watson.
» Definitions from Encyclopaedia Britannica 2008
…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!
