Discussed a case with company 'ABC' with a 'herbalife' or 'tupperware' like business model with 150000 agents and a turnover of 150000 agents. The EU would hold this company responsible to pay taxes over a portion of revenue generated through these agents. An earlier agreement a 58% consumption of own use was considered reasonable. How would you tackle this case: Brainstorm in our team was to use the [[5 why an how technique]]: * 5 Why and How? ** Who? *** Sampling **** Stratify for geography, revenue ** What? ** At what margin did you sell? *** Product consumption **** How frequently do you use the product? *** What is the shelf life time? *** Agent revenue **** How much is for own use? **** How much to famility and friends? **** How much are you able to sell to new customers? **** How much did you sell to a reseller? **** How much do you give away? **** Did you buy the products directly from ABC? **** How many product did you sell? **** How much products did you buy? **** How many product did you sell at reduced price? **** How much of your stock got stolen? **** How many customers do you have? **** How much of the ** Where? ** Why? ** How? Key points from the session: * How to get the data? * What is the average 'own use'? * What is the variance on the average? * What is the 95% [[Confidence interval]]? * Tax authorities would argue that the average would be closer to the left tail of the distribution.
