1.0 A consultant's job profile is different from a regular employee in many ways. The hours of work and responsibility levels are also different. We can also call it a case of PAY disparity according to role played by both.
2.0 Consultants are employed for making improvement or create development. We can say they are enablers or instrumental in doing certain things.Use of external expertise for internal gains by the organization, is one way of describing it.
3.0 An authorized signatory is supposed to represent his company. The client and consultant have their own companies and hence consultant cannot sign any instrument for the client's company.
4.0 Consultant's role is advisory. If a student fails teacher cannot be held responsible (save for exceptions). It is upto the client to take all of OR the part suggestions made by the consultant.Implementation is invariably client's purview. How well it is done is also a moot point.Once the client accepts the consultant's view, the responsibility becomes his. Many Consultants sign a contract where the limitations of their role and liability are clearly mentioned.
Your reply to your questioner is well set, relevant and appropriate. Some of my views are given.
Submission 1: - To be a consultant, needs unique quality i.e. subject knowledge as well communication skill both verbal and writing. Even if quality of knowledge and communication skill is not all rather should have courage to stand-up alone, wide contacts and known in sphere.
Moreover, there is no fixed earning but are self-content. Consultancy and Service are two different aspects, where a consultant can turn to service holder but difficult for a service holder to turn consultant.
Submission 2:- The change agent role is taken by the employee but not by the consultant. The consultant can only guide if consulted over the matters of change and confusion.
Submission 3:- The consultant cannot be signing authority for the company as an outsider. In other cases, if consultant’s agency has been appointed or work sublet to act as to deal with the bill processing and make payments on behalf of the client.
Submission 4:- The consultant can be held responsible where one undertook the execution and key result. It depends upon nature of work clients upload with consultant. Does a legal consultant held responsible for court cases? The answer is always “No”
