Business Analyst Interview Questions and Answers

This is the third article in our series of blog posts on Business Analyst interview questions and answers. You can read the scenario based interview questions and entry level business analyst interview questions and questions.

This post will be updated regularly with new questions. The questions get published on social media first and then get added to this first. Today, we are publishing the first question. The answer is also provided below:

Question 1: How do you calculate the project completion %age performance measure?

Consider the scenario below to answer the question

A software project is estimated to take 24 person-months of effort and 110 calendar days to finish. At a checkpoint, the project has consumed 16 person-months and 70 calendar days. What %age of the project is completed?

Note: This question can be easily customised to include a business analysis context. So don’t consider it to be a project management question.

This question needs some consideration to answer correctly. Lets consider the facts provided.

Total estimated effort = 24 PM (person-months)

Note: A person month means the amount of effort a person will spend in a month. Considering 22 working days, on average, it will be 22 days of work.

Effort spent at check point = 16 PM

So, the completion status = 16/24 = 66.67%.

But, this calculation has one major assumption. In this case, we are assuming that effort spent is equal to work completed. The effort spent at this checkpoint is indeed, 66.67%.

But, can we say that the team has also completed equivalent amount of work. It’s not easy to estimate.

So, how we estimate the correct status. This is done by estimating the effort required to complete the remaining work. Let’s consider two scenarios to understand it.

Scenario I

Total estimated effort = 24 PM (person-months)

Effort spent at check point = 16 PM

Remaining effort to complete = 10 PM (This could happen because of various reasons like resources leaving, challenging tasks etc.)

So, the completion status = 16 / (16+10) = 61.5%

Why did I consider (16+10) as total effort? That’s because ,at this checkpoint, 16 person months is already spent. Remaining work will take 10 person months, so the total effort = 16 +10 = 26 PM.

Scenario II

Total estimated effort = 24 PM (person-months)

Effort spent at check point = 16 PM

Remaining effort to complete = 6 PM (Not so frequent case but can happen)

So, the completion status = 16 / (16+6) = 71.7%

In this case, the total effort has reduced.

Question 2: What are Sprint Zero and Spikes?

Sprint Zero is the iteration that is used to get prepared for the project execution. It is certainly not part of Scrum rule books but has gained popularity.

Question 3: What is Review Efficiency?

Measuring the success of reviews is an important metric for a team. How do we measure the efficiency of reviews? Reviews are conducted throughout the life cycle of the project.

Question 4: What is Business process Re-Engineering (BPR)?

Business process is the way in which a business carries out its tasks to fulfil a goal and business process re-engineering is about changing the way business carries out the tasks to achieve same goal but with added benefits and reduced overheads.

Question 5: What is the difference between BPM and BPR?

Business Process Re-engineering (BPR) and Business Process Management (BPM) have the same goal of achieving organisational efficiency and effectiveness. The difference lies in the approach.

What are these and what is the difference between BPM and BPR?

Question 6: What is the difference between Incremental and Iterative development approaches?

The software development methodologies have evolved over the years. We started with sequential methodology (Waterfall) and adopted Incremental and Iterative methodologies, as methodologies evolved.

We use Incremental and Iterative methodologies interchangeably though they are different in their approaches. In this post, we would discuss the differences between Incremental and Iterative Methodologies.

These are approaches rather than specific methodologies. We can group SDLC methodologies under these approaches, just like we have Waterfall as a sequential methodology.
