One of the most systematic way that Sam could decide between the alternatives is through decision matrix or a decision tree analysis. In order to do that, he would need to list down the common outcomes for each of the decisions. For example, the outcomes could be
Demand for the organic and green products increases
Demand for organic and green product remains the same
Demand for organic and green product reduces
Next, Sam should estimate a payoff for each of the decisions and their respective outcomes. He should consider the impact from all angles and then consider the payoff. For example, if he works with another lawn service business, then his own father’s business may face stiff competition. There should be a monetary cost/benefit associated with it. Basically, Sam should convert all the outcomes into a numerical and quantifiable values. With this he could create a decision tree or a decision matrix.
In case he uses a decision tree, he should calculate the expected monetary value (EMV) for each of the decisions. Based on the EMVs he should choose the best possible value.
Also if he wants to consider his own style of decision making then he could use the decision matrix to determine if he wants to take an optimistic (Maximax), or pessimistic (Maximin) approach to each of the decisions.
A simple spreadsheet model with decision matrix and the alternative calculation should suffice.
