A column or set of columns that uniquely identifies each row in a table and cannot contain NULL.

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

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

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

A measurable value showing progress to a goal, such as conversion rate, average order value, cart abandonment rate and customer retention.

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

As a customer, I want to reset my password by email so that I can get back into my account. Acceptance criteria: • Reset link expires in 15 minutes • Password rules are shown while typing • A success message appears after reset

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

Get distinct user-month pairs, self-join or use LAG on month per user, and keep rows where the previous month is exactly one month earlier.

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

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

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.

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

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.

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

VLOOKUP or XLOOKUP, INDEX-MATCH, SUMIFS, COUNTIFS, IF, text functions, PivotTables and charts.

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

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

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.

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

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

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

Functions that summarise rows into a value, such as COUNT, SUM, AVG, MIN and MAX.

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

Split into revenue and cost, then revenue into price, volume and mix, and cost into fixed and variable; check internal factors and external market factors.

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.

Uncontrolled growth of requirements. Control it with a clear scope statement, change control process, impact analysis and sponsor approval for additions.

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

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

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

Separate inputs, calculations and outputs, link all formulas to input cells, add scenarios and checks, and avoid hard-coded numbers inside formulas.

Define a goal metric, a baseline and guardrail metrics, run an experiment or before-after comparison and review adoption, retention and revenue impact.

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.

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;

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

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.

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.

Structure it: households × car-owning share ÷ replacement cycle + first-time buyers + commercial fleet. State each assumption clearly and sanity-check the final number.

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

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

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.

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

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

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.

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

Compare the current state (as-is) with the desired state (to-be), list the gaps in process, people or technology, and plan actions to close them.

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.

Functional requirements describe what the system does (login, reports); non-functional ones describe how well it does it (speed, security, availability, usability).

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

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.

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.

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

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