The concept of EPM has been around for decades, and certainly from before the widespread use of computers. EPM processes and solutions were managed manually via meetings, phone calls, and discussions, and in the 1970s, the first EPM software applications became available, with accounting solutions collecting budgeting and financial information for use in reports.
Spreadsheets were introduced in the 1980s with software such as Lotus1-2-3 and VisiCalc, and they allowed finance teams to automate the process of creating budgets and reports creation as they finally replaced manual worksheets.
Once email became widespread in the 1990s, businesses became able to share spreadsheets, which helped them to collaborate more efficiently and helped them collect budgeting and reporting data more quickly from different people across the business.
Around the same time, the first EPM software packages such as IMRS Micro Control began automating the processes for financial consolidation and reporting.
