Question 1

An organization implements a new CRM software suite. If the software is technically robust but the staff lacks training, the business value $V$ can be modeled as $V = f(T, P, S)$, where $T$ is technology, $P$ is procedures, and $S$ is staff skill. Given $T=10$, $P=5$, and $S=0$, calculate the resulting business value if $V = T 	imes P 	imes S$.

Question 2

Zara maintains a failed product introduction rate of $R_z = 0.01$, while the industry average is $R_i = 0.10$. If a firm produces $N = 500$ new designs per season, calculate the difference in the number of failed products between Zara and the industry average: $\Delta F = N(R_i - R_z)$.

Accepted Answer

45

Question 3

A firm faces a commodity market where price $P$ is determined by $P = C + m$, where $C$ is the cost of production and $m$ is the margin. If a competitor introduces an operational efficiency that reduces $C$ by $20\%$, but the firm maintains its strategic positioning, which outcome is most likely?

Question 6

A company evaluates a proprietary algorithm using the VRIN framework. If the cost of imitation is $C_i = 1000$ and the cost of development is $C_d = 800$, calculate the imitation barrier index $I = \frac{C_i}{C_d}$. If $I > 1$, the resource is considered imperfectly imitable. Is this resource imperfectly imitable?

Accepted Answer

Yes

Question 7

Zara uses 'greige' fabric to allow for late-stage customization. If the cost of standard fabric is $C_s = €10$ and the cost of late-stage customization is $C_c = €5$, but this reduces inventory write-offs by $W = €20$ per unit, calculate the net profit impact $P = W - (C_s + C_c)$.

Question 8

A streaming service has a monthly churn rate of $c = 0.05$. If the current subscriber base is $S_0 = 100,000,000$ and the service adds $N = 5,000,000$ new subscribers per month, calculate the steady-state subscriber base $S_{\infty}$ where the number of lost subscribers equals the number of new subscribers.

Accepted Answer

100,000,000

Question 9

If the 'data flywheel' effect is modeled by the function $R(u) = k \cdot u^2$, where $R$ is the retention rate and $u$ is the number of users, and the current user base $u$ grows at a rate of $\frac{du}{dt} = \alpha u$, determine the rate of change of retention $\frac{dR}{dt}$ in terms of $u$ and $\alpha$.

Question 10

A company calculates the Customer Lifetime Value (CLV) using the formula $CLV = \frac{M}{c}$, where $M$ is the monthly margin per user and $c$ is the churn rate. If $M = €12$ and $c = 0.04$, calculate the total CLV.

Accepted Answer

€300

Question 11

In the context of the 'Long Tail' economic model, as the cost of digital storage and distribution approaches zero, the profit potential of niche content increases because the marginal cost of serving an additional user for a low-demand item is significantly lower than the marginal revenue generated by that user.

Option D

Question 13

If a platform's churn rate $c$ is reduced from $0.06$ to $0.04$ due to improved collaborative filtering, calculate the percentage increase in the average customer lifetime $L$, where $L = \frac{1}{c}$.

Accepted Answer

50%

Question 14

If the price of a computing unit drops from $1000 to $800, and the quantity demanded increases from 500 units to 700 units, calculate the price elasticity of demand $\eta$ using the formula $\eta = \frac{\Delta Q / Q}{\Delta P / P}$.
