4. e assignment for this lesson 16 14 How Do We Test Our Solution Once we have developed a solution the solution will need to be tested Solutions which appear to be good on paper often don t work out in application In some cases solutions can be tested on paper but most of the time solutions need to be tried out Here are some questions you might want to ask yourself when testing you solutions How sensitive is my solution to o Assumptions I made o Datal used How might I test my solution without making expensive and perhaps risky changes Have I considered everything important in my solution Is my solution worth the investment it will require to implement What might go wrong with my solution during and after implementation In very few cases can we be assured that the solution we developed will work exactly as we think it will That s why testing of the solution needs to be a part of our overall design How would you test your solution This is part of the assignment for this lesson 17 15 Design Tools for Testing Solutions There are a few design tools you can use for testing whether your solution is a good one Sensitivity analysis is good for looking at the impact of assumptions and data on the solution This is a simple approach you can use since it simply involves running your model again with different conditions When you find conditions that greatly affect you outcome you need to examine t

6. hem more carefully before you make recommendations Simulation is another way to test solutions Simulation is especially useful when the changes you recommend are likely to be costly or disruptive Simulation models do take time to develop Contingency analysis is more qualitative but it can be useful in testing you solution In this case you develop scenarios of possible things that could happen Then you work through how your solution approach will handle these possibilities Pilot testing is another approach you might use In this case you set up an experiment where you test your solution in a controlled environment While you can t test all contingencies a pilot test can be useful in identifying problems that might develop as you solution is implemented Conversations with those affected by your solution can help also be useful No one likes to change so you need to carefully think about whether a concern is a legitimate one or just a defense against change Finally every solution approach needs to have a cost benefit analysis performed A payback period needs to be calculated as part of the solution How will you test your solution This is part of the assignment for this lesson 18 16 How Do We Keep Our Solution Working When you are working through your solution you also need to think about how to make sure your solution is in effect after you are no longer involved Unless you incorporate the maintenance of your solution
7. into your design the problem is likely to reappear or mutate to some other problem Here are some questions you might ask about solution maintenance How can you be sure that your solution remains in effect How can you help those who will need to work with your solution to o keep it operating as intended o make changes as necessary How will the organization know when the system needs to be redesigned No solution remains forever People change circumstances change and requirements change Solutions have a useful life just like products do You need to think about review renewal and redesign as part of your overall approach 19 17 Design Tools for Review Renewal Redesign The design tools for review renewal redesign are fairly simple in concept but more difficult in application Here are some design tools you may want to use Review You can develop a simple audit procedure to be used with your solution The audit in this case would be a simple set of questions that the organization can use to ensure itself that the changes you developed stay in effect and are still appropriate Renewal Virtually every system you can design will need a user s manual This manual has two purposes Make sure that new employees understand what they need to do Helps owners of your solution make small changes as needed Redesign Every project needs to establish a redesign date when a professional will reexamine the system to se

13. rrent Situation The starting point for any project is to understand what the current situation is Often the problem you thought existed is a symptom for another problem In other cases you will find that you need to make fundamental changes in the current system before you can develop an overall solution approach You might want to ask these questions as part of your understanding of the current situation Place a checkmark in any box where you believe further analysis is needed Include this analysis in you assignment for this lesson Is the correct work being done O Are only necessary tasks being done O Is rework excessive O Is value added with every task Is the work being done efficiently O Are the employees sufficiently trained O Are the best work methods being used O Is the right equipment being used What is the effect of variability on the performance O Can variability be reduced O Are extra resources used to manage the variability Are the customers being served by the current situation O What does the customer value the most O Are we meeting the customer s requirements O Can we meet our customer requirements more efficiently What are the capabilities of the current situation O How many can we do O What different things can we do O What more could we do Is the current situation meeting expectations with regard to O Safety O Quality O On time performance O Cost 5 Design Tools for Analyzing the Cu
