Poorly defined scope of work
Late planning and approval of buys, impacting cost and quality
Resistance to commit budgets that forces advertisers to buy more expensive media later
Poor agency briefs or lack of agency involvement in the strategic planning process
Lack of proper approvals, creating financial exposure
Untimely or inadequate post buys
Billing and payment procedures that don't take industry practices into account
Most process issues can be easily addressed once they are identified.
