Anonymous A asked on Dec 13, 2020

Hi everyone,

I read a case on a producer of Business and First class plane seats. The interviewers wanted the candidate to estimate the market size. How would you approach the problem? I don't have the correction; just a few hints like the fact that the seats are renewed every 5 years and that the candidate used the number of planes produced by year apparently ...

Many thanks to all

I want to be notified about updates regarding this question via email

Existing Plane Market (Upkeep)

  • Estimate # of flights taken globally
    • Domestic vs. International
  • Extrapolate to # of planes
    • Domestic (medium size) vs International (large)
  • Estimate # of 1st/Business seats per plane
    • Domestic (almost 0 1st and 5-10 Biz), International (more)
  • Divide by 5 to get replacement rate

New Plane Market (Initial Install)

  • Lifecycle of a plane
  • 1 divide by lifecycle = x% of planes need to be replaced each year
  • Apply to # planes from above
  • Apply across biz/domestic numbers from #s above

And voila!

Hello!

First of all, the case would always have a little bit more info (e.g.,

  • Who is your client
  • What they want to achieve -maximize profits? maxime plane occupancy? etc.-
  • some basic data on the population

)

Once we have that, the approach would be clear.

For instance, if they want to maximize revenue, this would be more an optimization problem to be solved with an easy excel than a consulting case.

Hope it helps!

Cheers,

Clara
