Georoute is based on SMV standard minute values and is therefore based on observation by Industrial engineers. Each task has a SMV and I think the guide is located within the Phase 2 documents on the RM website.
I agree that phase 5 and 6 are the most important phase for us and is about testing the actual against the model.
Unfortunatly, the planners are able to play with the data used within the tool in order to get a result they want.
Some common practices are to set the terrain as flat, because walking on the flat is faster then walking up a hill, in my patch we have a spread sheet that is ment to calculate the adjustment for attendance calls (packets,tracked,records,specials,etc) but since it gives a SMV of 52sec per item confirms that the program has been set up wrong. I say this because 52sec is for a successful delivery, 76 sec is for a P739 (standard) 86 sec is for a P739 (all items with barcodes), so simple maths can tell you that the 52sec is wrong. I got over this problem by reducing the intervention totals by 25% I:E 100 items would be reduced to 75.
Before testing you would need to know the breakdown of the workload by stream for each walk and the process to deal with the excess items. The planners should be able to provide this info because it is vital for the testing phase. Up and down the country we have members being bullied and harrassed by managers when the workload presented to them is way over what was planned. The planner should provide a breakdown of the attendance calls per day say monday 27 tuesday 35, etc and in my units we have staff everyday given the managers excess items.
When things go wrong it is key to revisit all the base data, check APLUS measurements,delivery points,etc and if wrong put right, BAU stuff like cleaning,refueling seems to be overlooked by the planners and so if not planned within duty builder then failure is the result.
Getting the message to staff that for the next 12 weeks they must work to the standards and not come in early,weigh pouches, take M/R, WTL,etc....will help shape the end state duty set, hey I just saw a flying pig. But if you know people are cutting corners then log these issues and bring them into the reviews at 4/8/12 weeks.
The view of HQ is that if a rep isn't happy with the duty set then use the I/R framework.
Although the laser measurement roleout will coming to your D.O soon.
