Former Yahoo CEO Tim Sanders likens complex sales processes to videogames like Halo or World of Warcraft, in which your goal is to pass progressively more difficult levels and reach the top before your lives run out.He breaks the process down into four levels:Contact: connect with key decision-makers in the potential client company.Conceive: realize the perfect recipe for success in winning the deal.Convince: convince all the stakeholders that yours is the right solution to their need.Contract: train the legal team to think creatively even after the deal is made, to keep it sustainable for both sides.Each level poses its own challenges. Mastery of these skill requires strategic networking through layers of informers, influencers, and decision makers while relying on one’s deep company and product knowledge-(rather than charisma and facts).
