The arena of business competition is becoming ever faster and organizations need people prepared to lead the necessary adaptations and innovations. Coaching has been occupying a space in an effort to fulfill the mission of supporting the development of skills and behaviors in the Executive, so that companies can pursue their goals. For executives to experience the benefits of the process of coaching is essential that the coachee has clarity and understanding that there are behaviors to improve and a willingness to want to change and persist over time to the desired new behavior becomes a habit. The objective of this study is to analyze the importance and effectiveness of assessing the adaptive capacity and the individual s stage of change at the beginning and end of a coaching program as a strategic step for better assessment and planning process in order to choose more speed and security tools to be used in each case. To meet this goal, using the Stages of Change Scale / MES, which was developed by McConnaughy, Prochaska and Velicer (1983) and the Design Process Coaching, de Souza (2005), were followed eight executives in the process of skills development for three months. The results of this study suggest that executive coaching programs can be even more efficient by using assessment tools such as the Stages of Change Scale. Nevertheless, we can not lose sight that this is a process that requires extreme flexibility according to each case that is being conducted. Therefore it is desirable not to standardize the procedures in a generic way. Some limitations of the model were observed, as discussed in a separate chapter, and some recommendations from other studies and research were also mentioned.
