Legacy Tether

Why do enterprises keep their legacy systems? It is due to fear of change, cost or complacency?

In reality, it’s the fear of LOSS!

Systems contain the collective knowledge of the most experienced employees. Once the system is in place, many can utilise the expertise without fully understanding the logic. Over the years, the employees have become consumers of the knowledge rather than the custodian of it.

The older the system, the greater the gap between the individuals’ and the system’s knowledge.

In the last few decades, more emphasis is placed on documentation. However wonderful they may be, they NEVER contain the full and exact content of the logic that resides within the code. There are many reasons as to WHY that is the case. But primarily, it is because the code and documents residing on two independent parallel paths.

There are growing pressures to shame enterprises to eliminate their legacy systems without comprehension that the tether, keeping the legacies firmly in place, is their irreplaceable knowledge.

To unchain enterprises from their legacies an accurate recovery of forgotten legacy knowledge must become a priority.

Be deliberate.
