I will give you some answers.
OLPD - The uploads are incomplete and incorrect. My understanding was there is supposed to be a third party company that takes scanned images of packages without opld (or at least ones with hand written labels) and key enter the information in the system.
DOL - The traces for my drivers are VERY bad compared with how they are delivering.
Time Studies - I do not know when the last time study was done in my center, but I do know some numbers are VERY far off.
DMS - The software is klunky to use and is missing some important ease features. (such as a single click button to remove the air from a 20-30 seq add/cut, or the ability to direct map and add/cut from within DMS instead of running DMS and DPS at the same time to do daily adjustments.)
DPS - This software is worse for ease of use. When you make moves in the plan and have it automatically put them in order it often chuncks the moves you make by when you make them skipping over areas. It is impossible to update the maps that it is based off of. (I am using a map that was old when MS used it to make map point 3 years ago. MP2004)
Planning - I am using a time-in-transit guess of what is coming in by shear volume without respect to where that volume falls. That is like saying the dice have memory. if I flip a coin and it is heads 50 times in a row, the odds the next flip is heads is STILL 50%. The ie numbers are also very able. I have seen them adjust them (with little or no warning) to make plan without respect to if they are correct, or even possible.
Don't get me wrong, what we have is better than what we had. I can imagine running todays volume and dispatch with the tools from even a decade ago. I am just saying there is room for improvement.
Last but not least:
People - There is still resistance to PAS 2+ years after we went live. I hear almost every day this cut is not supposed to be on my route because it was not there 10 years ago. Things change and people need to accept the changes and work with them. Preload needs better methods training. We had almost a full week of cornerstone training, a week to learn the area, and then 4 more weeks (total 30 days) to become a good loader. Now they get 1 day of videos (if there is someone to show them) They load on day 2, and are expected to be loading the whole area buy the end of the week. The will be graded based on full production from about day 6 - 30 without any real training on the methods other than on the job. But the emphasis on the job is get the area down and get them off the clock, not teach them how.
All of these problems are interlocked. I have spent the last year trying to fix the problems that I have access to. So far no one above me will respond to inquiry/suggestions on the software. And less than 1 in 20 drivers is willing to sit with me to fix thier route. (The ones I have done, are VERY happy with the results) Most of the rest either grumble that it will never change, accept the daily drudge of what it is, or get actively mad because it wasn't right in the first place instead of accepting it is wrong and helping to fix it.
Making someone responsible for something without giving them any authority over it is almost as insane as doing the same thing over and over and expecting different results.
