As soon as a business notices that the same information is maintained in two places, the call for an integration follows almost automatically. That is often right and sometimes the most expensive way to prolong an organisational problem.
An integration does not remove double entry, it automates it. That is a difference: the second location still exists, it is simply no longer filled by hand. Everything attached to it remains, including the question of which version applies when the two drift apart.
Three questions before connecting
- 1.Does the second system really need this data, or was the copy created once because access to the first was inconvenient?
- 2.Which system leads? Without that decision, every integration becomes a reconciliation problem.
- 3.What happens on failure? Who notices that nothing has transferred since Tuesday?
The third question decides operational safety and is asked least often. An integration with no failure signal is more dangerous than none, because everyone relies on it while it stands still.
Where integration pays off first
From practice, the starting point is almost always where data crosses the border between two areas and gets copied by hand:
- From the quote into order processing: the same line items, typed twice.
- From time tracking into invoicing: monthly, under time pressure, error prone.
- From the contact form into customer management: otherwise the first contact stays in a mailbox.
- From the order into stock levels: otherwise no answer given to a customer is accurate.
What rarely pays off are connections between two systems doing the same job. There the integration is usually a substitute for deciding which of the two stays.
The simplest solution is often overlooked
Some double entry disappears without technology: through access for the person who so far had to ask and write things down. The reason for many copies is not a missing data flow but a missing permission. Checking that costs half an hour and, at best, saves a project.
We look at the handover points and say plainly which ones justify a connection and which are settled with a decision or a permission.
