Im my career I've seen a few projects that was "overengineered". Talented developers and architects designed complex architecture and used fancy solutions to achieve goals, which could be otherwise achieved much easier. This situation is quite common in various projects across the globe, from software projects to car industry to drugs research.
People usually think with "patterns". It's partly due to our system of education, where small children are teached that for each problem there is only one correct solution - the one on the back of your book ;). This education system limits our divergent thinking, which is essential for innovative thinking.
Standard Geolocation Field in Drupal 7 allows displaying of content only as a static image, using static Google Maps API. This solution is very limited: users can't scroll the map, zoom it nor change display type. I've implemented a patch which allows you to replace this image with dynamic, scrollable and zoomable map, which you know from many sites (including http://maps.google.com :) ).
To achieve positive results of your projects, you and your team must be well motivated. Without proper motivational mechanisms, people could easily lose their productivity, get apathetic and bored with your project.
