Study Notes
Service Engineering Basics - Lecture 13 - Service Business Case
- This lecture explores key concepts for understanding and managing a successful service business.
- Key figures and financial data were presented in the lecture, but no specific figures will be noted.
Lecture 12 Summary
- Iterative testing process considerations (desirability, feasibility, viability)
- Formulating testable, precise, and discrete hypotheses related to value proposition and business models.
- Prioritizing hypotheses by assessing levels of evidence and importance.
- Selecting experiments based on objective criteria (cost, evidence strength, setup time).
- Designing experiment sequences for various service types (B2B services, B2B software, B2C services).
- Conducting experiments (test card, learning card).
Learning Objectives - Page 3
- Importance of customer acquisition cost, customer churn, and customer lifetime value
- Minimum customer numbers needed for business profitability
- Assessing the viability of service business models
- Understanding top-down and bottom-up market sizing approaches
- Calculating profit and loss for a service idea
Motivation - Page 4
- Startups often fail due to a lack of sufficient customers, not just product issues.
- Early-stage focus should be on both product development and customer acquisition concurrently.
- Managing customer acquisition costs is crucial.
Customer Acquisition Costs by Industry - Page 5
- Customer acquisition costs vary significantly across industries.
- High costs in sectors like banking, telecom, and software tech are common.
Customer Revenue and Contribution Margin - Page 6
- Customer revenue and contribution margins change over time as customers are acquired and retained or lost.
- Initially, there are negative costs associated with customer acquisition, which is compounded if the acquisition is not successful.
- Maintaining customers over a longer period and continually generating revenue is necessary for profitability.
Customer churn rate in the United States in 2020 - Page 7
- Churn rates vary considerably across industries.
- Cable, financial, and online retail sectors have high churn rates, meaning customers are lost after relatively short time.
Question - Page 8
- The optimal time for investing in customer acquisition versus customer retention depends on the stage of a startup.
Acquisition vs. Retention - Page 9
- Investing in customer acquisition is important if there are no customers.
- Once a consistent customer base is established, maintaining that base will require more investment compared to acquiring new ones.
- Customer retention is often more cost-effective than acquisition.
Customer Lifetime Value (CLV) - Definition and objective - Page 10
- Customer lifetime value (CLV) is the total contribution from a customer to the company throughout their relationship.
- CLV is vital for understanding how much to invest in customer retention for positive ROI.
- Investments on profitable, high-value customers is key.
Learning Objectives - Page 11
- Importance of customer acquisition cost, churn, and lifetime value for maximizing profit.
- Minimum number of customers needed for business profitability.
- Assessing service business model viability.
- Understanding top-down and bottom-up market sizing.
- Calculating profit and loss for a service idea.
Calculating Service Cost and Revenue - Page 12
- Revenue is directly related to the number of customers.
- Fixed costs stay constant regardless of the customer count.
- Variable costs vary proportionally to the number of customers.
Service Profitability - Page 13
- A business is profitable when total revenue exceeds total costs (fixed costs + variable service cost per customer * number of customers).
Customers as drivers of revenue - Page 14
- Profitability depends on having a sufficient number of customers to cover the fixed and variable costs.
- Acquisition costs are a significant factor for generating the customer base.
Customer Dynamics - Pages 15-16
- Customer numbers change due to acquisition and churn, which depend on factors like firm efforts.
- Acquisition rate (new customers per month), and churn rate (customers lost per month) influence customer base dynamics.
Example - Page 17
- Illustrative example shows customer growth over time with constant acquisition and churn rates.
Asymptotic number of customers - Page 18
- The asymptotic number of customers (N∞) is achieved when the acquisition rate equals the churn rate multiplied by the asymptotic number of customers
Exercise - Customer Dynamics - Page 19
- Calculation of the number of customers needed for a service business in the long run, given churn, acquisition, cost per customer, and revenue data.
Exercise - Customer Lifetime - Page 22
- Estimating the average lifetime of a customer based on provided data for a service business.
Exercise - Customer Lifetime - Page 23
- Calculation of the average customer lifetime based on a service business's churn rate, acquisition cost, costs per customer, and revenue data.
Costs and revenue with acquisition - Page 24
- Calculating costs and revenue considers total cost (fixed costs, variable costs, and acquisition costs).
- Determining when to achieve profitability (total revenue > total costs).
Revenue vs. Cost - Page 25
- Profitability is determined when revenue per customer exceeds the sum of variable costs per customer and acquisition cost per customer multiplied by the churn rate.
- It's important to consider fixed costs as they do affect overall profitability.
Exercise - Profitability - Page 26
- Determining the minimum number of customers needed for a service business to be profitable, given fixed cost, acquisition cost, customer churn, and revenue per customer.
Exercise - CLV - Page 29
- Important ratio for service business valuation is customer lifetime value (CLV) to customer acquisition cost (CAC)
- CLV is calculated by multiplying the average customer revenue per year by the customer lifetime.
- The ratio greater than 1 typically means the business is profitable.
Exercise - CLV - Page 30
- The ratio of customers lifetime value to customer acquisition cost
- Estimating the customer lifetime value (CLV), expressed as L*(α-β)
Profit and loss model- Page 41
- Profit and loss statement is a summary of the revenues and cost of a service business for a specific time period (e.g., yearly, monthly)
- Calculating the EBITDA (earnings before interest, taxes, deprecation, and amortization) using total costs and total revenues for assessing profitability.
Summary - Page 42
- Summary of key concepts regarding customer acquisition cost, customer churn rate, customer lifetime value (CLV), assessment of service model viability, and market sizing approaches.
Top-Down Customer Acquisition Planning - Pages 33-34
- Top-down and bottom-up market sizing approaches to assess market capacity.
- Critical elements for effective market sizing are addressing customers' needs, understanding market contexts, utilizing proper tools and approaches, defining realistic expectations.
Bottom-up Approach to Market Sizing - Pages 35-36
- Bottom-up market sizing builds up from individual customer acquisition, not from overall market size.
- Using a sales funnel as a model to estimate the number of contacts necessary for acquiring new customers.
