Strategy question

You've shipped a bespoke Text2SQL workflow for one large customer, and leadership wants to know whether it should become a repeatable product. What criteria would you use to decide which components should be standardized into reusable software, which should stay configurable, and which should remain fully custom?

What this question tests

Tests deciding which parts of a bespoke technical workflow to standardize, keep configurable, or leave fully custom, using reusability and maintenance cost as the deciding criteria.

How to approach it

  1. Break the Text2SQL workflow into components: schema understanding and mapping, query generation, query validation and safety checks, and result formatting or explanation.
  2. Assess reusability per component: is schema mapping logic tied to this customer's specific database structure, or is the underlying approach (schema introspection, example-based grounding) generalizable across customers.
  3. Standardize components that are structurally similar across customers regardless of their specific schema, likely query generation and validation logic, since the core techniques don't change much between databases.
  4. Keep configurable the schema mapping and terminology layer, since every customer's database naming and business vocabulary differs meaningfully, but the underlying mapping mechanism can be shared.
  5. Keep fully custom only pieces tied to genuinely unique customer requirements, for example a bespoke approval workflow specific to this customer's compliance process.
  6. Validate the classification with a second customer's Text2SQL needs before fully committing engineering to productization, to catch components assumed reusable that actually aren't.
