While timing in sales, as in most everything, is, as they say, everything, it's very difficult to optimize for this (in an enterprise sale, hurricane forecasting, stock market).. The variables (and processes) that a team can most impact, are 1) The product itself, and 2) The relationship with customers and clients. Of course, each informs (and enhances) the other, but teams would do well to optimize for these two variables (easier said than done) -- good timing may end up being the byproduct of a great solution positioned well to key decision-makers who know and trust and love what you're building.
Yes - I'm just saying to consider also the timing factor.
Timing isn't a factor when you are there all the time. Check in with a potential client every 6 months. They may say no 9 times and then say yes on the 10th, because the timing is now right.
Same thing with any relationship, even personal ones. Persistence combined with patience is always a winning formula.
