Why integration projects stall and fail in MuleSoft's analysis: deadline-driven point-to-point shortcuts that become technical debt, siloed teams that rebuild the same integrations, and integration work that crowds out innovation, plus MuleSoft's three steps for reducing the debt.

- Certification: Salesforce MuleSoft Integration Foundations
- Exam section: Identify the roles, responsibilities, and lifecycle of a integration project
- Study guide: https://www.certifyforce.com/study-guide/mulesoft-integration-foundations

**Official exam objective:**

> Identify the common reasons that IT integration projects frequently fail.

## What the exam expects

- Recognize technical debt from deadline-driven point-to-point shortcuts and explain why its cost appears on the next project.
- Identify siloed development and missing reuse as reasons integration work keeps repeating and slowing down.
- Explain how integration work consumes IT time and leaves applications unconnected, so new initiatives stall.
- Reject false causes such as too few applications or a team that is simply too small.
- Name MuleSoft's three steps for reducing technical debt in order.

Key terms:
- **Technical debt**: extra future work a team creates for itself by taking a shortcut that is not the best long-run approach.
- **Point-to-point integration**: custom-coding each connection as a one-to-one link between two systems.
- **Siloed development**: teams building in isolation, so each project integrates the same applications again.
- **Reuse**: building an asset once so other projects and teams can discover and use it.
