CMA Final · Entrepreneurship and Startup
Idea to Action: formula sheet
Key formulas
- Core elements of entrepreneurship
- Opportunity + Resources + Risk-taking + Innovation = Venture creation
- A memory aid, not a mathematical formula. Use it to structure definition answers.
- Entrepreneur vs manager (main contrasts)
- Entrepreneur: creates, owns, bears risk, seeks profit and growth | Manager: runs, is employed, shares limited risk, earns salary
- Compare on the same parameters for each side: purpose, risk, reward, approach, ownership, time horizon.
- Traits vs skills
- Traits = personal qualities | Skills = learned abilities
- Do not mix them. Persistence is a trait. Bookkeeping is a skill.
- Idea versus opportunity
- Opportunity = Idea + Real customer need + Ability to deliver + Viable return
- A memory aid, not a statutory formula. Use it to explain why not every idea is an opportunity.
- SCAMPER
- Substitute, Combine, Adapt, Modify, Put to other use, Eliminate, Reverse (or Rearrange)
- Some texts say Modify/Magnify/Minify and Reverse/Rearrange. Use the version in your study material.
- Weighted screening score
- Score = Σ (weight × rating) for each criterion
- Weights should total 100% or 1. Choose the idea with the highest score, if it also passes the must-have criteria.
- Creativity versus innovation
- Innovation = Creativity + Implementation
- Use this when a question asks you to distinguish the two.
- Four feasibility studies
- Feasibility = Market + Technical + Financial + Legal
- Name all four in an answer. An idea can be weak in one area and still be rescued, but a failure in one area may stop the project.
- Payback period (simple)
- Payback period = Initial investment ÷ Annual net cash inflow
- Use only when yearly cash inflows are equal. Shorter payback means lower risk.
- Break-even units
- Break-even units = Fixed costs ÷ (Selling price per unit − Variable cost per unit)
- Shows how many units must be sold to cover costs. Compare it with realistic market demand.
- Simple ROI
- ROI = (Annual net profit ÷ Investment) × 100
- A quick financial feasibility check. It ignores time value of money.
- Fit sequence
- Problem-solution fit → MVP → Product-market fit
- Do not claim product-market fit before customers are actually buying and repeating.
- BMC nine blocks
- Customer Segments, Value Propositions, Channels, Customer Relationships, Revenue Streams, Key Resources, Key Activities, Key Partnerships, Cost Structure
- Revenue side is customers, value, channels, relationships, revenue. Operations side is resources, activities, partners, costs.
- Lean Canvas nine blocks
- Problem, Customer Segments, Unique Value Proposition, Solution, Channels, Revenue Streams, Cost Structure, Key Metrics, Unfair Advantage
- Four blocks differ from BMC: Problem, Solution, Key Metrics, Unfair Advantage.
- Unit profitability check
- Contribution per unit = Price per unit − Variable cost per unit
- Use it to test whether a revenue model can cover the cost structure.
- Customer economics check
- Customer Lifetime Value (LTV) ÷ Customer Acquisition Cost (CAC)
- A higher ratio shows healthier economics. A common rule of thumb is about 3 or more, but it is not a fixed law.
- Build-Measure-Learn cycle
- Build (MVP) → Measure (metrics) → Learn (persevere / pivot / stop) → repeat
- Aim to shorten the time taken to go once around the loop.
- Core business plan components
- Executive summary + Problem/Solution + Market + Competition + Marketing + Operations + Team + Financials + Funding ask + Risks
- Use this as a checklist for any 'prepare a business plan' question.
- MVP test rule
- MVP = smallest build that tests the riskiest assumption
- State the assumption, the test and the success measure.
- Break-even units
- Break-even units = Fixed costs ÷ (Selling price per unit − Variable cost per unit)
- Useful in the financial section of the plan to show viability.
- Post-money valuation
- Post-money valuation = Pre-money valuation + New investment
- Pre-money is the value before the investor puts money in.
- Investor's equity stake
- Stake % = New investment ÷ Post-money valuation × 100
- Use post-money, not pre-money, in the denominator.
- Founders' holding after a round
- Founders' new % = Old % × (1 − Stake % of new investor)
- Shows dilution when new shares are issued. Assumes no other changes, such as an option pool.
- Stage-to-source match
- Idea: bootstrapping/angels → Seed: angels, incubators → Series A: VCs → Later rounds: VCs, private equity, venture debt
- A general guide, not a fixed rule. Sources overlap in practice.
- Liability rule
- Proprietorship / general partnership = unlimited liability; LLP / OPC / company = limited liability
- Limited liability means the owner's loss is generally limited to capital contributed or shares held.
- Structure choice test
- Choice = liability + funding need + tax + control + compliance cost
- Use these five factors to justify any recommendation.
- Investor-readiness rule
- Equity shares can be issued only by a company
- An LLP or partnership cannot issue shares, so equity investors usually prefer a private limited company.
- DPIIT eligibility pattern
- Eligible entity type + within age limit + within turnover limit + not formed by splitting up or reconstructing an existing business + working on innovation or scalable model
- State the conditions in this pattern and confirm the exact limits from the current notification.
- IP protection map
- Invention → patent; brand → trademark; code and content → copyright; appearance → design
- Confidential know-how is protected through trade secret and non-disclosure agreements.
- Customer Acquisition Cost (CAC)
- CAC = Total sales and marketing spend ÷ Number of new customers acquired
- Use the same period for spend and customers.
- Customer Lifetime Value (LTV)
- LTV = Average revenue per customer per period × Gross margin % × Customer lifetime in periods
- Equivalent form: margin per period ÷ churn rate per period.
- LTV to CAC ratio
- LTV ÷ CAC
- A ratio of about 3 or more is often used as a rule of thumb. It is not a fixed law.
- CAC payback period
- CAC ÷ (Monthly revenue per customer × Gross margin %)
- Gives months to recover the acquisition cost.
- Net burn rate
- Net burn = Cash outflows − Cash inflows per month
- Gross burn is total monthly spending only.
- Runway
- Runway (months) = Cash balance ÷ Net monthly burn
- Assumes burn stays constant.
- Churn rate
- Churn % = Customers lost in period ÷ Customers at start of period × 100
- Average lifetime = 1 ÷ churn rate.
Quick revision
- The chapter follows one chain: mindset, idea, opportunity, validation, model, plan and MVP, funding, launch, scale, exit.
- An idea becomes an opportunity only when there is a real customer need that can be served profitably.
- Validate before you build: talk to customers and test assumptions early.
- Feasibility analysis checks whether the idea can work, for example on market, technical, financial and operational grounds.
- A lean canvas is a one-page model of problem, customer segments, value proposition, solution, channels, revenue, costs and key metrics.
- A business plan is a fuller document for planning and for convincing investors; the canvas is a quick working sketch.
- An MVP is the simplest version of the product that lets you test key assumptions with real users.
- Match the funding source to the stage and need; each source has a cost in money, control or both.
- Choose the legal structure with funding, liability, taxation and compliance in mind, and meet registration and filing duties on time.
- Growth needs systems, people and cash, not only more sales.
- Plan exit routes early, such as sale to another company, a public listing or a buyback, since investors expect them.
- In case answers, link every point to the facts given and end with a recommendation.
Common mistakes
- Treating every business owner as an entrepreneur. Fix: An entrepreneur innovates or creates new value. An owner who simply runs a routine business is closer to a business manager.
- Writing that entrepreneurs love risk and take any risk. Fix: Write calculated risk-taking: they assess, limit and plan for the downside.
- Treating idea and opportunity as the same thing. Fix: Always state that an opportunity needs a proven customer need, ability to deliver and viable return.
- Listing sources or techniques without applying them to the case. Fix: Link each point to a fact in the scenario, in one sentence each.
- Covering only market and finance and ignoring technical and legal feasibility. Fix: Always write all four studies, even a line each, and use case facts for each.
- Treating friends' and family's praise as validation. Fix: Prefer evidence of behaviour: pre-orders, paid pilots, repeat use. Interview real target customers about past behaviour.
- Treating business model and business plan as the same thing. Fix: Say the model is the logic of value creation and earning. The plan is the detailed document for execution and funding.
- Listing BMC blocks without applying them to the case. Fix: Fill each block with facts from the case, using the case's own names and figures.
- Treating an MVP as a cheap, low-quality final product. Fix: Say an MVP has the core features needed to test one assumption, and is built to learn, not to launch fully.
- Listing plan headings without applying them to the case. Fix: Add one line per component showing what it would say for this business.
Exam tips
- In the 2-mark MCQs, expect trait identification from a short behaviour. Match the action to one trait before reading the options.
- In case-based answers, quote the evidence with each trait. A bare list earns little.
- Prepare a ready five-point entrepreneur vs manager comparison. It is a frequent written question.
- Always say calculated risk and that the mindset can be developed. Examiners look for these.
- Keep traits and skills in separate lists and use the correct word for each.
- Define idea and opportunity in the first two lines. Examiners reward the distinction.
- In case questions, name the source or technique and tie it to a fact in the case.
- Learn SCAMPER, brainstorming and mind mapping well, as they are easy to apply.
