90 day trining plan. Steps/stages for the training

THESE were the instructions:
Your organization has never had any formal or informal training for new supervisors; when someone is promoted, they are immediately placed in the leadership position. This has recently become more important as your City Manager realizes over 75% of the supervisory staff will be eligible to retire within the next five years. Your task is to put together a "90 day" game plan for training potential new supervisors - this will then be used as a guideline for the department's succession planning efforts.
Your recommendations should include:
1.Steps/stages for the training (i.e. what do you want to happen in the first 30 days, 60 days, 90 days)
2.What type of information/classes would be presented? (Policies, SOP's, soft skills, etc.)
3.How would the training be delivered? (Classroom, online, video, OJT, etc.)
4.At the end of the 90 days, how would you know if the training was successful? (how to evaluate)
5.Research and cite at least one academic article that supports your recommendations.
