A month has gone by and during that month it has been a lot of reading articles. Much more than I originally thought. My planning report is basically out the window at this stage.
But this reading has been very interesting, I've looked into other research doing silimar studies but in other fields or software and by doing so I have learnt some new methodology that can be used for decision making and comparisons.
Brzozowski and Birfer (2017) lists in their article the different and most popular Multiple Criteria Decision Making (MCDM) that are used for comparing ERP systems, which feels like it could be applyed on other software comparisons as well. They do mention the Analytic Hierarchy Process (AHP) as the top one with Fuzzy AHP as the second, which is what my literature study has also shown to be the case. Even though I have run into Fuzzy AHP more than plain AHP. Good thing I like math... Also, please do not make me say those names out loud in the presentations because there's no way I'll be able to pronounce them correctly and I am sorry in advanve for butchering them.
AHP then, is a structured method for making complex decisions by breaking them down into smaller, more manageble parts. It works in four stages;
1. Structuring the problem as a hierarchy for comparison, including the goal for the decision, the criteria and the subcriteria and the options that are to be compared.
2. Compare each criteria pairwise by asking if criterion A is more important than criterion B and if so then by how much on a scale of 1 to 9 where 1 is equally important and 9 is extremly more important.
3. Calculate the comparisons into numerical weigths
4. Eacxh alternative is scored against the criteria which shows the best option.
Fuzzy AHP includes for the indecision that may accompany the comparison, that is that if you choose 3, you might mean 2, 3 or 4 and include these as a fuzzy numerical set to be counted with instead.
Basically it's a lot of math. And possibly a questionnaire in order to get more reliable weights for each criteria.
Well, that's it for now. Back to reading, writing and figuring out criteria!
