End users in one business area are unwilling to adopt a new finance management system (recently introduced by the innovation team), as they perceive that it is unnecessarily complicated and not useful. One of the end users in this business area has been very vocal and has been relying support from others since posting about it on the company’s intranet homepage.

The introduction finance system was initially supported by senior managers, but now users in other business area are also beginning to question whether they adopt the tool and are raising the issue with their managers.

The sponsor fully supports the decision to go ahead with the now tool and has made il very cleat to senior managers that he expects them to support this Initiative.

Which stakeholder management strategy SHOULD be taken with the senior managers?
