How and from which department(s) members of steering committee should be selected for ERP implementation of ERP? And who should head this committee?

HR Department

Human resourses management 

Three groups of internal people are usually needed in any ERP – a steering committee, project manager and subject matter experts.

The steering committee could be the management group or executive group for a small company. Larger companies will often delegate responsibility for projects to a steering committee whose members will include some members of the management or executive group.

Project manager is accountable for accomplishing the stated project objectives. Subject matter experts are those involved in the day-to-day work and who can speak in detail on the existing business process and all of its problems. They are heavy users of the system and are usually considered valuable resources.

this issue is outside my specialty

Committee should be selected  from , finance , production/Operations , Procurement , HR ,quality and IT department  it will  be headed by the IT department. Dedicated project manager is needed with full authority

Its generally a mix headed by a project manager under him would be the subject matter experts and offcorse a finance and human resourse personel who come in to the picture to design the game plan to handle the resistance to the implementation, employees affected change management and training I would suggest its a cross functional effort 

Committee should be based on Operations , finance , Purchase n Procurement , Assets Management  and IT sections which should be hedded by the IT section
