The Failure in Summary; The Disastrous Raid on Dieppe:

The Allied attack on Dieppe in 1942 was a costly failure. Worse, it was unnecessary. It was planned as a dress rehearsal for the Normandy invasion; however, the lessons learned at Dieppe and later applied at Normandy were already well known but had simply been forgotten. The attack was executed with valor and heroism but should never have been attempted.

Background
Several historians have given credit for the success of Operation OVERLORD to a much smaller-scale amphibious operation on a port along the west coast of France almost two years earlier. The raid on Dieppe, Operation JUBILEE, was executed on 19 August 1942 with combined British, Canadian, and American forces using naval, air, and ground combat services in a joint operation. The operation resulted in a tremendous loss of life, ships, and aircraft. It was by any measurement a complete failure. Were the lessons learned from this failed raid critical to subsequent battle plans, or could these lessons have been predicted?

The Success in Summary:

Lessons learned
Some have argued that the hard lessons learned at Dieppe in 1942 were put to good use later in the war. The amphibious assaults at North Africa were only three months away. The more successful Normandy landings would occur later in 1944. Others still maintain amphibious assaults had already been developed in a modern sense as early as Gallipoli, and the lessons allegedly learned at Dieppe would have been made in subsequent operations such as the invasion of Sicily (Operation HUSKY) or the landings at Salerno (Operation AVALANCHE) and Anzio (Operation SHINGLE).

Regardless, due to experience at Dieppe, the British developed a whole range of specialist armoured vehicles to allow their engineers to perform many if not all of their tasks under armour. These vehicles were used to great effect in the British and Canadian landing in Normandy in 1944. There were also huge improvements made in shore-to-sea communications, and many more and bigger ships available for ship-to-shore bombardment support.

Answer 2

Dieppe was a total failure except for the fact that it should the impossibility of capturing a major port on D-Day and the landing beach should be of firm sand rather than loose shingle.

Answer 3

It wasn't a success in any way.
The only 'valuable lesson' it taught was that it should never have been attempted.
There were not many wet eyes in Canada when Mountbatten met his end!
