Please read case background information below and download the excel document in attachment.
Background: each store (as specified in field “store_ID”) has multiple rate channels (as specified in field “rate_channel_id)” to sell their products. Rate channels get opened and ended now and then for various reasons. The longevity of a rate channel would largely impact the value of the rate channel for that store.
Objective: to calculate and demonstrate for each rate channel the distribution of longevity across stores, in data and graph.
A few special notes:
- since each rate channel for each store gets opened and closed now and then, some would be still active after being turned on and off a few times, while others might be terminated permanently already (as specified in “termination_flag”). Please take this into consideration when determining longevity of each rate channel by store
- please keep your calculation process in the sheet. If any coding is applied, please leave in your code
- manual calculation channel by channel store by store is discouraged
- for any questions, please feel free to feed back to recruiter and we will answer in time for your completion of the case study
