To help secure and grow your relationship with the client, demonstrating responsibility for both activity and results is critical.
 
One of the most common misconceptions about consultants is that they are simply "advice givers" holding no responsibility for getting things done. Here are three tips help to dispel this faulty perception:

Try taking the initiative, where appropriate. Don't wait for a client to call an initial meeting to get a project started. Perhaps you could provide your client with a draft proposal for a new initiative. You might also submit a draft agenda for a kick-off meeting including a proposed time, place and suggested participants. (Remember that the purpose here is to help your client move forward with ease and not to appear to be taking over!)
Project what the results of a proposed project or initiative will be to the organization in terms of reduced rejects, increased revenue, reduced costs, etc. Be as specific as you can by providing a range of likely outcomes in your projection of results.
Offer to oversee a planned project or play a specific role in its execution.

Tip: Demonstrating initiative and taking responsibility for tangible deliverables can result in you becoming a more active member of your client's team; one that is totally aligned with the organization's goals. This can also often result in more assignments being sent your way!
