This Southbeach model shows the potential harmful consequences of an unstructured approach combined with a lack of discipline and planning. It's a common picture. Let's break it down: Many people feel forced into this situation by the amount of work they receive and the amount of support from others they don't receive. This increasing work leads to increasing urgency which leads ultimately to dropping the ball (or less and less sleep, stress, less collaborative; more insular behaviour)... It has the further consequences that there is no time for planning, and no time for prioritising activities, leading to a reactive behaviour that becomes more random with time.
The Southbeach approach can be used to re-establish the discipline necessary to deal with complex situations and high workloads. It is a structured approach that enables you to break your problems down into manageable chunks that can be shared with others. Structuring thought, planning, design, work, and collaboration in this way can create more reuse in everything you do and can reduce the workload for others, giving them more time to help reduce the workload for you.
Another benefit of this collaborative approach is the wealth of experience and different ideas and approaches that can be brought to bear. More information, with more techniques for combining it enables better decision making to enable you and others to focus on what is important to get results and achieve your goals.
