Your argument is that Microsoft Office is not thriving because of institutional knowledge, then you proceed to prove that it is institutional knowledge that makes it a valuable tool.<p>If your arguments are:
1) Most users can pick it up easily due to familiarity.
2) Excel is a general tool usable by many disparate groups in the organization.
3) Excel is the lingua franca of manipulating data within the organization.<p>Then it seems to me that these would fall under the category of &#x27;institutional knowledge&#x27;, and you are in effect arguing that it is thriving because of institutional knowledge.
