I have designed and delivered Tableau Solutions for a variety of clients, and while each client requirements differ, I generally fit them into 5 different categories; in this article, I will discuss the characteristics of each of the 5 categories, my main ideas and considerations.

The Problem During a recent engagement a client asked a question I hear occasionally regarding Tableau which basically boiled down to: “How do I show marks for the percentile ranks of my customers by Sales?”
The client wanted to aggregate their measure, we’re using Superstore Sales here, up to the Customer level (Superstore stores information at a per item per order level so it’s an excellent proxy) then assign customers to 10th percentile buckets. Once assigned, the client wanted to do analysis on various relevant measures like Profit and Order Quantity (in this example). The main challenge with the ask is how the data is shaped. Much like Superstore we were faced with data that was aggregated at a lower granularity than how we intended to judge the customer worth. Fortunately with Tableau v9 we can achieve the desired result using the FIXED level of detail function! The Solution The first step we need to do was define Customer Worth as the lifetime total Sales from the Customer. Table Calculation Functions - Tableau.

There has been a conversation floating around on how to successfully navigate around different sheets of a workbook.

However it is possible and below is an example of a menu system within a Tableau workbook which uses actions to navigate from sheet to sheet.

One will need to be created for each target dashboard plus an extra one for the return to main menu if you want. The text itself is created through a simple calculated field with the string written inside and dropped onto the label shelf.
Create a menu dashboard to drop all the link worksheets onto, format to taste and you’re ready to go. Tableau Zen. Alan Smithee Presents: Changing Viz Types with Dashboard Containers and Parameters.
