Will there be shift toward project-based pricing (or outcome-based pricing) services engagements?

Agreed with colleagues answers

Buyers have discovered that paying by the hour creates a disincentive for innovation and efficiency. The longer it takes the vendor, the more they earn. However, for the client, the faster they get a solution, the better. The hourly-vendor who delivers the most efficiently makes the least money. In2014, the top performing professional services organizations will start shifting as much as30% of their billing to project-based, or outcome-based pricing (with assumptions to protect themselves). Buyers want results, and they’ll pay for it. However, the savvy customer rarely wants to sign a blank check for hours of time without a defined outcome.

Yes indeed, people became more sensitive to efficiency.

I also support the answer of Mr. Vrindavan.

In Project based pricing service engagements, the provider not only provides service in time but also updates the machinery and equipment with the updated technology.
