Check market size (population, online ordering share), competition, restaurant supply, unit economics per order, CAC and payback period. Propose a pilot with clear success metrics.

ROI = (incremental profit - campaign cost) / campaign cost. Measure incremental sales using a control group or before-after comparison.

Goal Seek (find the input for a target output), Data Tables (see outputs for many inputs) and Scenario Manager (save best, base and worst cases).

Map the funnel, find the biggest drop-off, check usability and load time, run A/B tests on fixes and track conversion lift.

WITH m AS (SELECT month, SUM(amount) AS rev FROM orders GROUP BY month) SELECT month, rev, ROUND(100.0 * (rev - LAG(rev) OVER (ORDER BY month)) / LAG(rev) OVER (ORDER BY month), 1) AS mom_pct FROM m;

A named temporary result introduced with WITH that makes long queries readable and reusable in the same statement.

Anyone affected by or influencing the project: sponsors, product owners, end users, developers, testers, operations and customers.

Identifying everyone affected by the project and mapping their influence and interest to decide how to communicate with and involve each group.

Both look up values flexibly; XLOOKUP is simpler with built-in not-found handling, while INDEX-MATCH works in older Excel versions.

A table linking each requirement to design, test cases and delivery status, ensuring nothing is missed and helping assess change impact.

Top-down: two-wheeler market x EV share x addressable segment. Bottom-up: target households x adoption rate x price. Compare both for a sanity check.

A framework listing internal Strengths and Weaknesses and external Opportunities and Threats to assess a project or business position.

Strengths and Weaknesses are internal; Opportunities and Threats are external. Example: S = strong faculty, W = low brand awareness, O = AI upskilling demand, T = free online content.

A query nested inside another, used for filtering or calculating values such as customers whose spend is above the average.

Use MoSCoW (Must, Should, Could, Won't), value versus effort scoring or the Kano model, agreed with stakeholders based on business value and risk.

Aggregate revenue per month and use LAG(revenue) OVER (ORDER BY month) to compute (revenue - previous) / previous.

Check data accuracy, then segment by city, restaurant, time and user type; look at supply, delivery time, pricing, competitors and seasonality before proposing fixes.

Break-even units = Fixed costs ÷ (Price − Variable cost per unit). Add a data table to test different price and volume scenarios.

They help the Product Owner refine the backlog, write stories and acceptance criteria, clarify details with developers and support testing and demos.

An early assessment of whether a proposed solution is technically, economically, operationally and legally viable before committing budget.

Combine cost-plus, competitor benchmarks and willingness to pay from research, test tiers with experiments and check margin and churn impact.

It breaks a top metric into drivers: Revenue = Users × Conversion × AOV; Users = New + Returning, and so on. It shows which lever to pull and where a drop came from.

Prepare clean data, build PivotTables and PivotCharts, add KPI cards and slicers, and arrange everything on one sheet with a clear layout.

Clear, testable conditions a story must meet to be accepted, often written as Given-When-Then scenarios.

Clarify the underlying goals, present data and trade-offs, facilitate a joint session, escalate to the sponsor if needed and document the agreed decision.

Waterfall runs fixed phases one after another with requirements frozen early. Agile delivers in short sprints with continuous feedback, so requirements can change. In Agile, BAs maintain the backlog and user stories.

Population about 20 million, adult tea drinkers about 50%, cups bought outside per person around 1 on average. This gives roughly 10 million cups, then adjust for offices and stalls.

A BRD states what the business needs and why. An FRD details how the system should behave to meet those needs (functional specifications).

Finding the underlying reason for a problem using the 5 Whys, fishbone diagrams or Pareto analysis, then fixing the cause not the symptom.

A UML diagram showing actors and the actions (use cases) they perform with the system, giving a quick view of scope.

An Excel add-in for building data models with relationships and DAX measures over millions of rows, beyond normal worksheet limits.

About 20 million people, roughly 10% order pizza on a weekend, about 1 pizza per 2 people in an order. This gives roughly 1 million pizzas, adjusted for outlets and delivery capacity.

CAGR = (End value / Start value)^(1/years) - 1, entered as =(B2/A2)^(1/n)-1.

A short requirement written as 'As a user, I want X so that Y', backed by acceptance criteria. Good stories follow INVEST: independent, negotiable, valuable, estimable, small and testable.

Review > Protect Sheet or Workbook with a password, lock cells, hide formulas and allow only selected cells to be edited.

Testing how changes in key inputs such as price or volume affect the output, in Excel using data tables or scenario manager.

Define churn, analyse who leaves and why, segment customers, find drivers through data and surveys, design retention offers and measure uplift with a control group.

XLOOKUP can look left or right, uses exact match by default, returns a custom value if nothing is found and doesn't break when columns move. VLOOKUP only looks right and needs a column number.

GROUP BY aggregates rows by column; WHERE filters before grouping and HAVING filters after, using aggregate conditions.

Look at the cost side: heavier discounts, higher CAC, logistics costs, product mix shifting to low-margin items, one-time expenses or pricing changes. Break contribution margin down by segment.

The sales volume where total revenue equals total cost. It equals fixed cost divided by contribution margin per unit.

A BA bridges business and technology: gathers requirements, analyses data and processes, documents BRD/FRD and makes sure the final solution actually solves the business problem.

The smallest version of a product with enough features to deliver value and gather real user feedback before investing more.

Clarify the scope, break the problem into logical parts, state assumptions with round numbers, compute step by step and sanity-check the answer.

A what-if tool that recalculates a formula for different inputs, for example loan payments across different rates and tenures.

Pareto principle: about 80% of outcomes come from 20% of causes, such as most revenue from a few customers or most defects from a few issues.

Score them with RICE or value-vs-effort, align with goals, consider dependencies and risks, validate with stakeholders, then use MoSCoW for the release plan.

Check row counts against the source, nulls, duplicates on keys, value ranges, date coverage and that totals reconcile with finance reports.

Variance = Actual - Budget, shown as amount and percentage, with conditional formatting to flag large gaps and comments on the drivers.

The total profit expected from a customer over the relationship, roughly average margin x purchase frequency x lifespan, compared with acquisition cost.

Profit = Revenue minus Cost, where revenue = price x volume and cost = fixed + variable. Split each part to find which one explains a change.

The product backlog is the ordered list of all desired work; the sprint backlog is the subset the team commits to in the current sprint.

Product, Price, Place and Promotion, the levers a business uses to bring an offering to market.

Use STAR: Situation, Task, Action, Result. Show that you listened, found the underlying goal, used data to align people and reached a documented decision.

Every KPI is a metric, but a KPI is tied directly to a strategic goal (e.g. monthly churn). A metric can be any measurement (e.g. page views).

INNER returns only matching rows; LEFT returns all rows from the left table and NULLs where there is no match.

Number of outlets x daily customers x average bill x operating days, then validate using footfall, peak hours and similar chains.

Stakeholders and the sponsor review the Business Requirements Document for completeness and accuracy, and the business owner gives formal sign-off before design begins.

Agile delivers value in small increments with feedback. Scrum organises work in sprints with planning, daily stand-ups, review and retrospective, led by a Scrum Master and Product Owner.

SUM(sales) per category divided by SUM(SUM(sales)) OVER () and multiplied by 100 gives each category's share of the total.

Create a line or column chart of actuals and add the target as another series formatted as a line.

Assess market size and demand, customer need, competition, unit economics, capabilities, risks and strategic fit, then test with a pilot before scale-up.

Log the change, assess impact on scope, cost and timeline, get approval through change control or backlog grooming, and update documents and stakeholders.

Interviews, workshops, surveys, observation, document analysis, prototyping and brainstorming, chosen according to stakeholders and project stage.

Create a table, insert a PivotTable, drag region to rows, product to columns, sales to values, and add slicers for month or channel.

COUNT(*) counts all rows; COUNT(column) counts only rows where that column is not NULL.

Define named scenarios such as best, base and worst with different input values and compare the outputs in a summary report.

AVG ignores NULLs; use COALESCE(col, 0) if NULLs should count as zero, depending on the business meaning.
