Great TT Kathyrn – great question Dale.
I’ll take a stab at the theory as I understand it and then give you our real world practice.
Theory: You’re the Project Manager or Project Financial Manager on a large multi-million dollar project in a fiscally mature organization where your project’s EV data is closely monitored. EV data is only as accurate as what’s posted. If division X met all of last month’s deliverables but their time isn’t posted, or the hardware has arrived but the finance month end runs a month behind and these costs haven’t posted to your project yet, calculating through ‘today’ will be missing actuals, impacting the EV data making Clarity present 'untrustworthy' data. Nobody wants this, but Clarity can’t guess at what ‘done’ is. Someone or Something has to tell it. Being able to control the ‘As Of’ date is the PM or PFM’s quality control tool – allowing them to say “I approve this project to be EV evaluated through this date”. This works great.
IRL: We’re not that cool or mature but we do like much of the EV information (BCWS, ACWP & SPI/CPI trending). We also like to keep it simple.
- We’re only tracking labor costs at this time (timesheets & rate matrix).
- We’re good at getting our timesheets in. Our mantra is “honest, accurate, and approved”. I like to add “…and posted”. The ‘accounting’ system is therefore trustworthy.
We post time every Tuesday at 1AM. Every Tuesday at 2AM we run a job that automagically updates the ‘As Of’ date on active projects to the date of last posted time (Friday of Previous Week), then we run the EV jobs.
Voilà – trustworthy, consistent, automagic EV data with no effort from the PMs. We’re been doing this for a couple years – I don’t think anyone thinks this operates anyway other than automagic.
HTH.
