Measuring Productivity - EXCEL/ACCESS? : Advice Appreciated

[monksrig_5]

I would appreciate help/guidance. I'm currently working on a project to measure how effective people are against a number of activities. I want to measure how often people do these key tasks and what the outcomes are (i.e. how often the undertake the tasks (outputs and maintaining Competence) and how successful they are (productivity and effectiveness). I plan to do this for around 200-300 people and have considered whether this sits best as a spread sheet or is it something more suited to a database. If it is a spread sheet, which I'm drawn to, how can I prevent the spread sheet from becoming too bulky to manage on screen. If a spread sheet is the best option it will take time to draft and populate with the required formulae etc. Has anyone undertaken a similar task and if so what are the learning points I should steer clear of?? Thanks
