Executive service questions

Questions leaders ask before approving Data Architecture Design

This section is written for decision-makers who need to understand the business reason, risk, first step and expected outcome before approving a CRM, data or automation engagement.

Why should leadership prioritise this now?

Data Architecture Design should become a priority when the current process is limiting revenue visibility, slowing execution or forcing teams into manual workarounds.

  • Leadership cannot get trusted answers quickly
  • Teams rely on spreadsheets outside the CRM
  • Data, reporting or workflow issues are now affecting growth

What is the executive risk of waiting?

Waiting usually increases hidden cost because poor process and data quality compound across reporting, automation, migration and user adoption.

  • Fields added without a model
  • No single source of truth
  • Scaling breaks the configuration

What should a strong vendor plan include?

A strong plan should connect business goals to architecture, process design, data ownership, implementation sequence, QA and adoption.

  • Current-state diagnosis before build
  • Target operating model and implementation roadmap
  • Validation, reporting and adoption checkpoints

When should a CRO, COO or CRM Director approve this?

Approve the work when the business problem is clear, the cost of inaction is visible and the scope can be tied to revenue, efficiency or governance outcomes.

  • The business owner agrees on the desired outcome
  • The current setup is blocking decisions or execution
  • There is a realistic roadmap and delivery model

What should the first 30 days deliver?

The first 30 days should deliver a decision-ready plan, not vague recommendations.

  • Discovery workshop and system review
  • Risk-ranked issue backlog
  • Implementation roadmap with owners and priorities

What information should you prepare?

Prepare enough context to explain the business impact, current technical state and decision process.

  • Current platform and reporting pain
  • Known data, integration and adoption issues
  • Stakeholders, timeline, budget stage and constraints

Use these answers to decide whether this page matches your current CRM problem. If it does, ask Celumai for a focused audit and implementation plan.

Business challenges

Why Data Architecture Design projects fail

01

Fields added without a model

Admins add fields reactively to solve immediate problems. 2 years later there are 400 fields, 60% unused, and nobody knows what anything means.

02

No single source of truth

Account, Contact, and Lead objects all store conflicting versions of the same customer. Reports require manual reconciliation every time.

03

Scaling breaks the configuration

What works for 50 users fails at 500. Object relationships, sharing rules, and automation logic need to be redesigned from scratch.

04

Integration topology not planned

Every new integration is bolted on separately. No common data layer. Middleware becomes spaghetti. Changes to one system break three others.

What is included

The architecture Celumai designed has scaled from 200 to 2,000 users without a single structural change. That is what good data modelling looks like.
