01 / Domain

Consulting Methodology & GAP Analysis

Walk me through your 'Discovery Phase' for a new enterprise client.

ANS:I start by identifying key stakeholders. I document the 'As-Is' process, identify pain points, and then map them to Odoo's 'To-Be' process. I focus on high-level workflows first (Sales, Purchase, Accounting) before diving into granular details.

How do you handle a 'GAP' where Odoo standard doesn't meet the requirement?

ANS:I follow the hierarchy: 1. Configuration. 2. Workaround. 3. App Store (OCA). 4. Customization (as a last resort).

What is a 'User Acceptance Test' (UAT) and why is it critical?

ANS:UAT is where actual business users test the system in a staging environment. It ensures the configuration meets business needs and secures 'buy-in' before Go-Live.

How do you manage 'Scope Creep' during implementation?

ANS:By maintaining a strict 'Change Request' process. Any requirement outside the initial SOW is documented, estimated, and approved as a separate phase.

Explain the importance of 'Data Cleaning' before migration.
