Well it is better if what is to make fast & efficient spreadsheets and not fancy documents with embedded fonts, lots of styling and containers for things that do not belong in spreadsheets like photos & images.
Took 5 years for a friend to get his department to switch from MS Office to Open Office.
Big drop in productivity for the first year while the "Resistance" fought a rear guard battle.
Massive drop in computer & network problems made mangement happy with the first year.
!0 years down the track & the staff refused to go back to MS when they got a new director who wanted to stamp his authority on the department.
Estimated savings were in the order of $2,000,000 in licencing fees and around the same for IT downtime.
Staff satisfaction & lack of frustration is not directly measurable but it would be up there with the other figures.
Last place I had a delivery contract with went over to MS NAVS for all their warehouse & billing soft wear.
They sacked 2 employees who became so frustrated with the new system perpetually hanging that they threw their computers off their desks.
Latter on they added the PDT option to "increase productivity " and ended up putting on 4 more drivers and 6 more loaders because the system could not cope.
OTOH any board member can log in at any time day or night and see exactly where the company was, when the system crashed this time.
Laughable as the whole justification was it would intergrate the 3 separate software applications they were using and allow the head office to sack 4 staff.
It never occurred to any of the computer illeterate top management that if every part of the process from taking the orders through to final billing was done by 1 system, any glitch in any part brings the whole shooting match to a stand still.
