Often we will think again or change our mind basically by the adoption of a different opinion or plan.  A decision to proceed with a specific activity (e.g., product purchase, vacation, job change) might be altered.

Once a decision is made the plan on how to achieve the associated defined goals can be developed.  During planning, factors impacting the feasibility of the original decision could cause us to change our minds.

For Example

You may decide to purchase a new television.  You undertake a search for products for a while and make a selection.

Before you actually make the purchase you become aware of a far superior product, ie, through an acquaintance, direct advertising or another unplanned channel.

This new information can easily cause you to change your mind.  If you have not initiated the purchase of the first choice this change is probably easily made.

Occasionally changing your mind can have greater impact.  In these cases the value equation comes into play.  Simply put, is the effort and impact of the change worth it.

Subjective versus Objective

Often a truly objective analysis is overridden by emotional factors modification of the original decisions might not be the most logical approach.

In these cases the value largely derives from satisfying the emotional need.  Sometimes when there are a number of stakeholders this approach is not satisfactory to all and can leave some mystified.

When changing a decision, unless only you are impacted, it is always best to communicate the rationale for the change to everyone that is impacted.
