VISA Web based Multi-Criteria Decision Making Software. V·I·S·A software is for decisions with multiple, tough to balance, factors; for decisions where no option matches all of the criteria perfectly; or for decisions where more than one person has a say in how the decision is made. It does not tell you the ”right answer”, it lets everyone involved see for themselves what the best overall decision is, weighing up all the factors using a considered and sound process. V·I·S·A also documents how that decision was made and why it was the right outcome for future reference.
