Process Improvement Case Study

Part of the Business Analyst Roadmap

In short

Find a slow, annoying process, prove why it's slow, and propose a better one with numbers. Few portfolio pieces show business impact this clearly, and you can do it with any office around you.

Document a real or hypothetical process improvement — As-Is mapping, gap analysis, and a To-Be recommendation with expected impact, showing Phase 4's process modeling skills.

Think of it like this

Fixing the ticket counter queue

One long line at the railway booking window, because seniors, tatkal and enquiries all wait together. Split it into an enquiry desk and two booking lines, and waiting drops. Your case study does this: show the jam, fix the flow, measure the gain.

The big ideas

What you need to know

Before and after maps

Put As-Is and To-Be diagrams side by side. The reader should spot the change in seconds.

Numbers, even rough ones

Time a few real cases. 'About 4 days, based on 12 requests I tracked' beats 'it's slow'.

Root causes, not symptoms

Explain why the delay happens: a missing form, an extra approval, unclear ownership.

A realistic rollout

Add who needs to agree, quick wins first, and how you'd track whether it worked.

See it in code

Walk through the code

1/3Inputs: your measured baseline, your estimate and the volume.

A tiny impact model. Simple, transparent maths is fine, as long as you say where each input came from.

Save yourself the pain

Common mistakes

Oops

Only showing the To-Be process.

Do this instead

Show the As-Is with its problems first. The improvement only makes sense next to the before.

Oops

Claiming '80% faster' with no data.

Do this instead

Base estimates on observed cases and list your assumptions. Honest maths builds trust.

Your mission

Milestone 1: the As-Is

~40 min

Quick check

Your To-Be removes one approval step. What makes the case study convincing?

Go deeper

  1. 1Choose a process you have genuine insight into, ideally one with a real inefficiency.
  2. 2Show your As-Is and To-Be maps side by side with clear reasoning for the changes.
  3. 3Estimate the expected impact (time saved, cost reduced) of your proposed improvement.
