Methods to Enhance Knowledge Discovery with Persona-Pushed Methods – Atlan

Visitor weblog by Jacob Frackson, Observe Lead at Montreal Analytics

Knowledge discovery and personas: Completely different personas use information otherwise and that ought to be effectively understood in your information stack. Finance and product each care about clients, however how are you going to current these two completely different variants with out inflicting confusion? From entry management to naming conventions, we’ll clarify how personas could make your information stack extra usable and scalable.


The probabilities are practically limitless in the case of your information, however how do you select what to construct and design for? Who will get to drive when designing your information pipeline and information mannequin?

A single company-wide imaginative and prescient is commonly out of contact with the actual wants, and individual-oriented design is commonly unrealistic, so the place does that go away us? By defining and leveraging your inside personas, you and your information group can strike the precise stability between these two extremes and design an information stack that basically works. 


What do these issues appear to be in motion and are they current at your group? Let’s use the fictional Poutine Store challenge for example. Poutine Store is an inside challenge by Montreal Analytics the place we’ve constructed an ecommerce web site for a enterprise that sells Poutine, a standard dish from Quebec manufactured from french fries, cheese curds and gravy. Poutine Store strives to resolve the worldwide poutine provide chain, one on-line order at a time. We’ll use this instance to showcase these two information group extremes and the way personas may also help them higher manage their information mannequin.

Overly generic, company-level information fashions are superficial and will result in miscommunications or misinterpretations. Whereas some company-wide metrics might be very highly effective and assist tie everybody collectively – akin to Prospects Served All Time or Month-to-month Buyer Progress – others might be an accident ready to occur. With income, for instance, it’s attainable to keep up a single common definition, however what occurs when the finance group needs to begin reporting on income web of cancellations or refunds? And what if gross sales needs to maneuver the information up and begin counting income when the contract is signed, not when the fee is collected? Nicely, now the straightforward time period “income” isn’t practically enough for all these potential analyses and use instances! How can we determine who will get to make use of “income” and what does everybody else do?

On the different finish of the spectrum, if everyone seems to be left to outline income on their very own we’ve both low adoption or much more miscommunication! With much less construction, many potential information stakeholders shall be pushed out resulting from their lack of familiarity with the device or insecurity of their expertise. Then again, in the event that they do begin defining their very own metrics and fashions it’s inevitable that they are going to change into increasingly complicated, creating loads of potential for misalignment: Do you may have the identical filters? Do you utilize the identical timeframe? Are you utilizing the identical mixture? Certain, it may be very helpful and versatile that anybody can now discover totally and outline their very own metrics, however your constructing blocks are too small and also you don’t have enough guardrails in place!

Defining your Personas

Personas sit between these two extremes, so let’s discuss defining them.

Personas are teams of a number of stakeholders which are characterised by their shared relationship to information: How do they use information? How do they discuss information? What assumptions have they got about that information? In additional complicated organizations you possibly can have overlapping personas and even nested personas. Knowledge-savvy personas typically result in sub-personas too: for instance, if Operations on the Poutine Store may be very refined of their utilization of knowledge, subdivisions could also be wanted to correctly outline the variations between how the prep group and the supply group take into consideration scheduling and success metrics.

Personas are sometimes outlined by the information they’re thinking about, the language they use to explain that information, and the applying of that information. When eager about your personas, if you happen to don’t have already got an thought, the very best place to begin is your org chart. If that doesn’t really feel enough, look to your greatest information shoppers at present and see what defines their personas. 

For the Poutine Store, there are 4 enterprise items: Finance, Product, Operations, and Advertising and marketing, and inside that, Operations additionally has three principal features of Prep, Supply, and Assist. This can be a fairly good place to begin for our personas, understanding that we are able to at all times add or subdivide sooner or later!

Design Rules

With personas recognized, the information mannequin design can now be up to date and tuned. Above, we noticed that completely different personas are thinking about completely different topics and use completely different terminology to speak about these topics; what can we do to accommodate that? Listed below are 4 steps that any group can begin making use of:


Begin by reviewing your information namespace. How do you title your schemas? Tables? Columns? How do you title the folders in your BI Instrument? Basically, how do you select distinctive names for all issues information? 

Names ought to be distinctive, pattern-driven, and significant; when selecting names, take into consideration what different names or entities is perhaps competing for that title and select names that don’t trigger rivalry or create confusion. 

Listed below are a number of examples for column-naming:

  • All timestamp columns ought to be named prior to now tense and suffixed with `_at`: created_at, updated_at, ordered_at
  • All booleans ought to be prefixed with is_ or has_: is_active, has_subscription
  • All pure keys ought to be suffixed by `_id` and all surrogate keys ought to be suffixed by `_sk`: order_id, item_id, order_item_sk

Design Language

As soon as the names and their patterns have been settled, it’s time to consider every thing in between: how ought to dashboards be designed for various personas? How ought to documentation norms differ throughout personas? What are the design guidelines for every persona when working with information?

Design language contains naming conventions, but it surely additionally contains structure, aggregation sorts, visualization sorts, documentation size and content material, and extra. What works for one persona goes to really feel solely misplaced for one more.

Listed below are a number of examples of metric naming conventions:

  • Product: Consumer Progress, Lifetime Worth; these names are concise and full of which means.
  • Operations: Time to Package deal (from Order Positioned, Min.), Time to Ship (from Order Packaged, Min.); these names are verbose, particular, and descriptive.

Entry and Group

Namespaces and design language have been reviewed and up to date, and now we want to consider day-to-day utilization and entry. What does every persona want entry to and what don’t they? Limiting entry, be it via strict permissions or just by organizing content material to maneuver it off of individuals’s homepages, could be a big assist. It lightens the cognitive load of utilizing the platform by displaying you issues in your personal design language first, and it helps reduce the danger of misusing or misinterpreting information.

Folder buildings, schemas, and in some instances entry grants, can all assist enhance the information workflow to your personas. 

Automation and Course of

We’ve overhauled our group, and now we have to keep it. Defining processes and including automation is commonly essential to sustaining your information techniques. On this regard, there are numerous completely different strategies at your disposal, starting from out-of-the-box instruments

Listed below are a number of frequent examples:

  1. Utilizing MR/PR templates so as to add table- and column-level naming critiques to your code evaluate course of
  2. Utilizing dashboards like these obtainable in Looker to evaluate unused content material
  3. Utilizing dbt to check your data schema for naming conference consistency
  4. Utilizing numerous instruments like Slido’s dbt-coverage device to measure your documentation or testing protection
  5. Utilizing Atlan to create personalised workspaces and routinely keep information techniques with automated column descriptions, documentation, high quality checks, and extra.


Due to the steps above, the Poutine Store’s information mannequin is extra attuned to its group. Advertising and marketing is ready to use information successfully, Operations is ready to use information successfully, and neither has to compromise!

Future information pipelines and fashions will be capable of push this boundary even additional, from personas to sub-personas and even personalised information mannequin experiences. Diving head-first into individualized information fashions is a recipe for catastrophe, however sooner or later, and by leveraging metadata, we’ll be capable of slowly push in the direction of that degree of personalization. In the end, we would like our information fashions to be helpful and adaptable. Immediately, personas are an important method, however sooner or later they’ll be just one device in our toolbelt.
