Questions & explanations
1. How do you measure the conversion rate from free to paid in a freemium model?
Conversion rate is the percentage of free users who become paying customers during a given period. To measure, track the number of free users at the start and how many upgrade within a month or quarter. For example, if 1,000 free users exist and 50 upgrade in a month, the conversion rate is 5%. You can also measure conversion by cohort to see if newer users behave differently. It is important to define what counts as a 'paying' user—anyone who subscribes or makes a one-time payment. Monitoring this rate over time shows if changes to the product or marketing are working. A low conversion rate may indicate that the free version is too generous or the premium offer is not compelling.
2. Describe the servitization continuum from pure product to pure service. Give an example of a company at the 'product with services' stage and one at the 'outcome-based' stage.
The continuum ranges from selling a standalone product (e.g., a car) to selling the outcome of using the product (e.g., mobility). In between is 'product with services', like a car with a warranty and maintenance package. For example, an industrial tool company that sells drills with a repair contract is at the product-with-services stage. A company that sells 'holes drilled per month' and provides the drill, operator, and maintenance is at the outcome-based stage, like a farming equipment manufacturer that sells 'crop yield per acre' and provides tractors, seeds, and advice. The further along, the more responsibility the provider takes, and the more performance-based the payment.
3. A company is negotiating an SLA with a call center vendor. Describe two pitfalls they should avoid in SLA design and how to address them.
One pitfall is defining metrics that are too easy to meet, like average call time under 10 minutes, which could be gamed by rushing calls. Address it by including a distribution metric, e.g., 90% of calls answered within 5 minutes, and a customer satisfaction score. Another pitfall is not specifying exclusions clearly, like excluding calls during power outages. Without exclusions, the vendor could claim every downtime is an exclusion. Address it by listing specific exclusions (e.g., scheduled maintenance) and requiring proof. Also, ensure the SLA includes a process for disputes and periodic review. Avoid vague terms like 'best effort' and instead use concrete numbers.
4. Compare selling a product (like a printer) with selling an outcome (like printed pages). Describe a challenge the company faces when moving along the servitization continuum.
When selling a printer, the company earns revenue once and has no ongoing responsibility except warranty. When selling printed pages, the company must manage supplies, maintenance, and sometimes even paper. A challenge is that the company now bears the cost of usage and must accurately predict consumption to price the outcome. For example, if a customer prints more than expected, the company's costs rise but revenue is fixed per page. The company also needs new capabilities like fleet management and service logistics. However, it can build long-term relationships and get steady revenue. The shift requires a change in mindset from product-centric to service-centric.
5. A jet engine manufacturer shifts from selling engines to selling 'thrust by the hour'. Explain what this means and give one benefit for the customer.
Instead of buying the engine, the customer pays for each hour of thrust the engine delivers. The manufacturer retains ownership and is responsible for maintenance, repairs, and ensuring the engine is always available. For the customer, this reduces large upfront costs and shifts operational risk to the manufacturer. For example, an airline pays only when the engine is actually providing thrust during flight. If the engine fails or needs maintenance, the cost is borne by the manufacturer. This outcome-based contract incentivizes the manufacturer to build reliable, efficient engines because they pay for downtime. It aligns both parties around the outcome of uptime.
6. Compare service process reengineering with continuous improvement (like Kaizen). Give an example of a change that would be reengineering, and one that would be continuous improvement.
Reengineering is a radical redesign that breaks old rules, while continuous improvement makes small, ongoing tweaks. For a bank loan process, reengineering might eliminate the loan officer role entirely by using an automated credit-scoring system that approves loans instantly. That is a huge change in structure. In contrast, continuous improvement might reduce form-filling time by 10% by rearranging fields. Reengineering aims for 70-100% improvement, while continuous improvement targets 5-10% each time. Both are useful, but reengineering is riskier and more disruptive. A company might first try continuous improvement, then reengineer if gains are not enough.
7. How do you optimize the conversion funnel in a freemium model?
Optimization involves analyzing each step from sign-up to purchase and reducing drop-offs. First, identify the key stages: sign-up, first use, engagement, and upgrade offer. Use data to see where users are leaving most. Then test changes like simplifying sign-up, improving features, or adjusting the upgrade prompt. A/B testing different messages or price points can find the most effective approach. It is also important to re-engage users who stopped using the free version. Personalization, such as offering a relevant upgrade at the right moment, can boost conversions. Continuous monitoring and iteration are needed because user behavior changes over time.
8. How can a business that currently uses multichannel service transition to an omnichannel approach?
First, the business needs to connect its different systems so they share customer data in real time. This might mean using a single customer database that every channel can access. Next, the company should train staff to see the full customer history no matter how the customer contacts them. It is also important to design a consistent experience across channels, like the same tone and level of help. The business can start by integrating the most used channels, like phone and email. Finally, it should listen to customer feedback to find any gaps and fix them. This step-by-step change can turn a multichannel setup into a smooth omnichannel experience.
9. An elevator company moves from selling elevators to selling 'vertical transportation as a service'. Give an example of what the contract might include and how payment works.
The contract might specify that the customer pays a monthly fee based on the number of floors traveled or the number of passengers moved. The elevator company installs and owns the elevator, and is responsible for all maintenance, repairs, and even modernization. For example, a building pays $0.10 per ride or $500 per month for unlimited use. If the elevator breaks down, the company must fix it quickly, often within a few hours, or face penalties. This outcome-based model ensures the building always has working elevators without capital investment. The company earns more if the elevator is used heavily, so it designs for reliability and efficiency.
10. Compare how ESG analytics differs from traditional financial analytics in retail reporting.
Traditional financial analytics focuses on profit, revenue, and costs – money matters. ESG analytics looks at non-financial impacts like carbon emissions, diversity, and ethical practices. Financial reports are required by law, while ESG reports are often voluntary but increasingly demanded by investors. The data types differ: financial uses currency values, ESG uses physical units (tons of CO2, number of women in management). ESG analytics often involves estimating and modeling because some data is hard to measure directly, whereas financial data comes from transactions. Both are used to guide strategy, but ESG adds a broader responsibility lens.
11. Compare a modular service design with an integrated (monolithic) design for a hotel booking system. Give one advantage of modularity and one advantage of integration.
A modular hotel booking system might have separate modules for room inventory, pricing, and payments. An advantage is that the pricing module can be replaced with a dynamic pricing algorithm without changing the rest. The integrated system has everything in one piece, so changes are harder. However, an advantage of integration is that data flows faster because there are no boundaries between modules. For example, real-time availability updates might be simpler in an integrated system. Also, integration avoids the complexity of managing many modules and their interfaces. The choice depends on whether flexibility or simplicity is more important.
12. Explain what outcome-based contracting is and give an example of a risk that the provider takes that it didn't have when selling the product alone.
Outcome-based contracting means the provider is paid for achieving a specific result, not for delivering a product. For example, a lighting company might contract to provide a certain level of illumination in a factory, and is paid per unit of light output, not per light bulb. A risk the provider takes is that if the customer's building changes or energy prices rise, the provider's cost to deliver the outcome may increase, but the revenue is fixed per outcome. Also, if the equipment fails more than expected, the provider bears the repair cost. The provider must invest in reliable technology and may need to monitor usage to manage these risks.
