Hiring an executive coach for yourself or for your employees is a very wise investment. Through an excellent executive coaching process you can reach new levels with your organization with a 400 to 900% return on your investment in many cases. There are factors though that might not get the job done all the way to the desired end.
An executive coach is a human, who can work and produce, and sometimes get sick, emotional disturbed, get personally turned off from the job, and their life might come to an end before they finish what they started. In any of these cases you'll have to hire a new executive coach. The new coach will have to go through the notes left behind by the previous coach, carry out a reassessment for the candidates and the organization, and maybe have a different view on how to handle this job.
All of this is a wasted time, which means wasted money for you. Besides, they new coach has to get used to your organization and vice versa, which might not be easy this time, especially that your employees have already started to trust and get used to the system and the plan put by the previous coach. Another wasted energy that also means wasted money for you.
The solution is very simple. Instead of hiring an individual executive coach you can hire an executive coaching firm. Those firms hire executive coaches, train them on the firm's policy, and the client who hires the firm is now the responsibility of the firm not the individual coach.
How this helps?
The firm might assign one executive coach to do your coaching job, but on the back end there is a team of executives planning and making the policy and the strategy that this individual coach will stick to. This way if this individual coach is not available to finish the job another one can be provided who can carry on from the point at which the first coach has stopped.
Another advantage is that an executive coaching firm holds the individual coaches accountable for their results, and they follow up with them and their clients to make sure everything is going according to the plan put by the firm in the first place. the result is that you don't have just one mind doing the job, you have several fine-tuned minds behind the job.
Also in a firm all the coaches are certified and have standards to follow. You can rest assured that the coach on the job really qualifies for it.
