Case Study 01

Operational Reliability

Multiple systems (Odoo, Zapier, Google Cloud) needed deterministic, auditable workflows with fewer silent failures.

Intervention 01

Zapier Trigger Reliability & Failure Diagnosis

• Audited Zapier run history to separate test noise from real failures

Read more

Strategy & Action

  • • Audited Zapier run history to separate test noise from real failures
  • • Identified cases where Odoo webhooks never fired, not where Zapier failed
  • • Mapped which Odoo events should trigger Zaps vs which actually did
  • • Documented why “missing Zap runs” ≠ “Zapier error”

Operational Impact

  • → Eliminated false blame on Zapier
  • → Created a repeatable troubleshooting playbook
  • → Improved stakeholder trust in automation reliability

Intervention 02

Odoo Webhook & Automation Architecture Review

Read more

Strategy & Action

  • • Verified Odoo automation domains (model, stage, project filters)
  • • Confirmed limitations: Odoo does not log outbound webhook payloads
  • • Refactored automation logic to reduce silent no-ops
  • • Ensured stage changes, task creation, and field updates triggered correctly

Operational Impact

  • → Fewer “nothing happened” scenarios
  • → Clearer understanding of where failures occur (Odoo vs Zapier)

Intervention 03

KPI Pipeline Engineering
