Question: at work is your agenda private or public? E.g., can colleagues see your agenda (subject + location) within, for instance, Outlook?
What arguments can I give to higher management or to colleagues to open up their agenda?
At the work (2000 people) of a friend everyone has a open agenda, even the CEO. While at my work (12.000 people) by default everyone has their agenda on private mode. Because of this it is often really hard to find a time slot for a meeting which suits for all stakeholders when you want to plan a meeting.
As an employee this bothers me a lot since I it takes a lot of time to find a suitable time slot. I will have to contact people by phone, go to their desk etc. simply to check if they are actually available.
When people's agenda would be open, subject + location of the meeting would be visible. It would be a lot easier to check if people are available, and to minimize disturbance for the whole group. I would be able to make an assessment based on everyone's agenda. When for instance, one stakeholder would have a 1-on-1 meeting, I would only have to ask him, if it is possible to change his meeting. Or when someone simply stated.
Of course you could reason that people also have private appointments or they have company sensitive meetings. In that case, at least in Outlook, people can still mark them as private.
