There are typically four general stages involved in solving a problem:
1. Define the problem. This will include clarity of definition, collecting data that relates to the problem, investigating the problem, which can involve asking a range of people of their experience of the problem or carrying out more detailed research, and identifying the cause or causes of the problem. It can be a good idea to present the definition of the problem to someone who has not experienced it beforehand to see if it is clear, concise and readily understood.
2. Generate potential alternative solutions. Try and be creative and innovative in thinking about alternatives to what may typically be anticipated. Thinking about the consequences of the alternatives can also help to narrow down those that will be unlikely for further consideration. Undertaking brainstorming, or similar activities, can help to focus on the problem at hand and try and get a range of people with different interest involved to help provide a broad perspective on ideas.
3. Evaluate each potential solution and select the most favourable one/s. Determining criteria for evaluation and any weightings for these will need to be carefully considered, ensuring opinions of all concerned are treated fairly and respectfully. Criteria for evaluation might include total cost, affordability, cost-effectiveness, environmental impact, impact on product quality, impact on staffing retention and motivation, timeliness, impact on safety, longevity, intuitiveness, availability of replacement parts, availability of third-party support, along with many other possible criteria depending on the problem being investigated.
4. Implement the chosen solutions, monitor and review, through evaluation, after a planned period of time. The success of the solution can be based on the outcome related to the evaluated criteria from stage three. Have the results met or exceeded expectations, or is there still a problem which exists, or has the solution introduced another problem, through unintended consequences, which now needs solving? If the solution has been successful, then continue to review its progress as part of a continuous improvement cycle.
