I see more and more decision makers and stakeholders than before… bigger deals can be tough and take time to push through the business dependent on the level of pain… that said, if you see or people are being strung alone that could be down to XP or skills on how to manage the opp… the best sales folk will hold the customer to account, get them to agree upon actions and follow through, if they are taking the piss it might be time to qualify it out or escalate to someone that can help drive it… If you are sitting between the engineers and sales teams, it might be an idea to flag / record time spent in the presales phase and the resource its taking… some of the numbers and effort will be shocking… been there a few times! And it’s painful, I totally get where you are coming from, cheers
