Do you compare going to a bargain store and pick some things, to going to a multi service shop with a printable design or document in a flash memory in a certain format and some level of confidentiality to be printed in a desired quality?
Training for retail chains shops’ employees is always easy, there is no heavy knowledge to learn and the starter’s peers are easily guide them to the process, then no extra skills need to be acquired. The case is different if you provide services that needs extra knowledge, like the well known Officeworks, they have printing, copying, canvas art, digital photography, online services… etc, these services need a certain level of training, and there is a considerable probability to have bugs and technical difficulties over time, many staff have solutions or workarounds, while others in other branches may still struggling. They also sell electronic devices which needs knowledge about their specifications because many customers will come with a certain level of knowledge to discuses with the staff. In such retail stores wikis have a remarkable potential, since the staff have an access to computers, starting a wiki as a basic documentation and reference to what to how to complete the tasks is better than a static documentation, giving the users the ability to update this documentation and to add to it will make it always up to date without an extra effort from the headquarters, and will make it very helpful. Staff will refer to it on any technical issue, even if they didn’t find the solution and found it later somewhere else, writing it to the wiki will be a reference in the future for them and all the branches’ staff. If they found many solutions to many problems they will probably tend to add to it and improve it as a pay back.
Wikis are well known in the cubic offices environment where employees stair at their computers most of the time, but it will be useful also on the retail stores if the staff have an easy access to computers and their work needs verity and up to date skills. This strategy will not have a direct effect, it will pay off while the time passes and the staff of all branches have a collective intelligence and a cumulative knowledge that makes printing such a canvas (which was done only by dedicated artists few decades ago) much easier:
