My company is focusing more on Outbound Telemarketing and we have implementing the traditional "carrot and stick" management approach of rewards / penalty system as an Extrinsic mechanism.
My current practice is we pay our staff competitively in our local market with insurance and health care benefits. To drive their sales performance, we attach a SPIFF incentives of cash and/or gift certificates reward to the Best Team and Top Performing Call Agents on a weekly basis. As of now, apparently it is working as we are hitting 6-8 SPD (sales per day per agent) with a minimum target of 6 spd. I am not sure its sustainability. We are giving Career Development and progress path with opportunities to move up the ladder.

Now with Intrinsic motivation part (with longer term impact), I need some typical examples of "lessons learned" sharing from your part so that we can apply the "How To" in my company. Surely, it will drive more long term positive effect to the organization. Thanks in advance
