While I was reviewing the IT annual plan this week I remembered some of the recurring challenges that exist with annual plans. One of the biggest challenges is determining how to service and solution work that is not originally on the plan. The usual work initiators that meet this criterion are new business won, compliance/regulatory requirements, and custom requests from existing clients. When this happens, managers and business leaders have to determine how to shift priorities and possibly even postpone goals on the annual plan until the next year. It happens every year.
Leaving contingency funds for the unexpected is a key concept in personal finance budgeting. A best practice with budgeting is to leave margin between your income and monthly obligations. This margin can be used for savings as well as unexpected expenses that occur during the month.
What if we created business plans that provided margin between the capacity of the organization and number of goals/objectives on the plan? For IT, I would call this Technical Margin, but a more general term is Work Margin.
The tendency with annual plans is to fill them with objectives that are beyond the capacity of the organization. Our appetites are always bigger than what we can accomplish and we tend to underestimate the time projects will take. Even without new unplanned work we have challenges accomplishing everything on the plan. If our plan leaves margin then it allows us to adjust goals easier during the year when new work appears.
In 1992 Ward Cunningham first noted a comparison between software code and debt that became known as technical debt. For IT leaders, creating technical margin is a perfect way to have some time to eliminate technical debt as well as service the unexpected.
In a formula the amount of work margin is variable depending on the amount of planned work you choose to put in the annual plan. The decision is based on how much risk tolerance you have for unplanned work adjustments through the course of the year and how much room you want to leave for retiring technical debt.
Onward and upward!
