How can integration not succeed?

Integration - rule is a principle that if the parties to a contract have embodied their agreement in a final document, then any other action or statement is without effect and is immaterial in determining the terms of the contract.

Explanation:

1

Develop consensus around business needs.

Bridging disparate systems almost always involves addressing the needs of multiple departments. It's critical to build inter-departmental consensus as to what those needs are - and what the priority needs are. Without clarity around desired outcomes, engineering solutions can become a sprawling process that leads to project overruns. Systems integration is as much an art as a science, and negotiating the goals for the project in advance is key to success.

2

Integrate inter-departmental protections.

Part of the art of reconciling different systems and needs is successfully negotiating necessary protections. There may be technical, regulatory or political reasons for not sharing the full breadth of data across all departments. Limiting access appropriately is a critical part of ensuring long-term success for your custom systems integration project.

3

Embrace detail. Document everything. Discard nothing.

Information that doesn't seem important at the outset may prove critical further down the line. As the systems integration project expands, people usually uncover new needs and issues. Your systems integration project can end up looking very different as it moves from the planning stage to and through the development stage.

4

Build in dynamism and post-project costs.

Change is a constant when it comes to systems integration. New problems and needs often crop up after the project launch. Unfortunately, the skills needed to adequately address them are rare. For most clients, ongoing maintenance and improvements need to be built into the project from the initial planning stages.

5

Plan for emerging technologies.

The longevity of any custom systems integration is dependent on its ability to adapt to emerging technology. Keeping the system modular and flexible enhances the shelf life of an integration. This equates to better ROI and a happier team over the long term. Insist on looking beyond immediate needs, and plan for change - it's inevitable.
