I'm especially interested in connecting headcount planning with company objectives. Thanks!
Now depending on your work environment you can do one of two things:
- Work environment is still "healthy": Show your gantt chart to your boss as a justification for the resource count addition but highly stress that the dates are not accurate or even valid estimates. That is what a dedicated planning session is for.
- Work environment is not "healthy"/a bureaucracy: Come up with whatever justification you can that validates the number you came up with in a gantt chart (aka parallel construction) but don't show the gantt chart. They will take those numbers as gospel no matter what you say.
Our platform allows engineers/entrepreneurs to launch point solutions (meaning it solves one specific use case as compared to breadth of an ERP) to enterprise customers. If you're interested in chatting happy to discuss and help those trying to improve the lives of those trying to disrupt the forecasting & analysis world (regardless of whether it has anything to do with our company).
More than the tool, what matters is the discipline of all functions (i.e., departments) agreeing on the business processes such as annual budgeting, quarterly/monthly forecasting, feedback loops to account for recent trends and key program-wise/location-wise assumptions (eg. attrition, shrinkage, training yield, ramp-up/learning curve etc.,).
Then, you build up a bottom-up forecast with those key assumptions that translates to revenue and expenses to build a P&L forecast.
A spreadsheet offers the most flexibility. Again, more than the tool, it is the process and the discipline (includes agreeing on standards, lead-times etc.,).
This culture and practices also varies from organization to organization and in practice, in large organizations, you have the legacy of acquisitions that cause a diverse set of practices. While a common tool might help these organizations streamline and standardize the headcount planning process, the challenges are not technical but human and cultural.
