Pros
P&G is truly committed to its purpose of improving lives of the world's consumers. This gives meaning to the work and a clear value by which to judge one's work. While P&G definitely has the best products in its categories, there is still ample opportunity to better understand how these products fit into consumer's lives and can make it better beyond the purely functional. Being as globally diversified and diversified across consumer goods categories as P&G is, it is a very solid and steady company that will always have opportunities to grow. Employees are seen and treated as the most valuable assets of the company and due to the common set of ethical values, it is very easy to work with any other P&Ger anywhere in the world. there is always the opportunity to create depth of knowledge in a certain category or to move between categories.
Cons
Being as big as P&G is and having been around for so long, P&G tends to be conservative in its decision-making and it often takes a long time until we catch on to new trends. It can be bureaucratic and it's not always the most qualified people who are the final decision-makers. Also, there is a tendency to spend a long time on alignment and hence decision making by committee.
