What processes in Marketing most impact sales effectiveness and efficiency?

Marketing sometimes gets this feedback anecdotally from sales but usually nothing measureable to ensure they are producing the right materials. Having the RIGHT marketing materials in the hands of your sales team has a huge impact on their efficiency and overall effectiveness with prospects!

When marketing has the insight and knowledge to know which assets are being used and at what stage of the sales process, they can produce more effective marketing assets so that the sales team can just "grab-and-go", instead of spending time tailoring existing marketing collateral, making the whole process more efficient.
