Results-oriented in my experience usually means that the output of your efforts is what your productivity will be measured by. I've had the (mis)fortune of working in such areas and it's had the following implications:
Gung-Hoism. As results being the main metric of performance, team members are usually driven harder to deliver. Either by peer pressure or insecurity,developers will bang out code at breakneck speed,stock brokers will make (huge,risky) trades. All to get results
Competition. Related to or as a result of (1), competition in such environments tends to be fierce. Whether it's among teammates or between departments, the organisation can easily become a shark pool. While a healthy level of competition is necessary for any successful organization; back stabbing, ass covering and email warfare will generate friction between the elements of an organization. Any organization will become counter productive pretty quickly under such conditions. It sounds bad but this quality will breed
a fighter in you. You'll develop a can do attitude like no other place can impart
Merit based rewards. A result driven environment is not kind to lazy staff. Or politicians. Or incompetence. You're going to be rewarded based on what you've done (successfully) and not by being teacher's pet.
Work volume. This is one thing I believe the "Results-oriented" and "Fast-paced" phrases have in common; there will be plenty to do in a result-oriented environment. You'll get a lot of action, if. you're in the right place at the right time. As a result of 1 and 2, it's not uncommon to have turf wars between managers and departmental heads. With regards to projects and budgets, if you find yourself on the team of the bigger shark, you'll have plenty to sink your teeth into. If you're on the losing side, you'll spend a lot of time sitting on your hands.
