Risk Assessment Detailed Design Review MSD 1 5/3/2013
Risk Item Effect Cause Likelihood Severity Importance Describe the risk briefly What is the effect on any or all of the project deliverables if the cause actually happens? What are the possible cause(s) of this risk? L*S What action(s) will you take (and by when) to prevent, reduce the impact of, or transfer the risk of this occurring? Customer Priority Changes Delay of project progression Poor communication/ Uncertainty 2 2 4 Have weekly meetings with guide and keep both sides updated on project Unreliable Suppliers Disrupt our project budget plan, and delay design process. Parts are not available through Kodak 1 2 2 Take initiative and request parts from Guide, and compile a list of what we have and what needs to be ordered Skill Set Alters design slightly, and will change list of parts that we need to order Only one EE to develop controls, and rest of team members have little experience in that field 1 2 2 Group EE seeks feedback from EE department to make sure concepts are feasible 4 Team Dysfunction Poor team chemistry will demotivate group and may cause delays in deliverables. Differences in opinions/ concepts 1 1 1 Reach consensus on ideas/concepts to make sure everybody is on board 5 Unavailability May deliverables Poor communications/ Illness 2 1 2 Let group know if/ why you can’t attend meetings. Plan ahead. Poor Communication People may not know current tasks Lack of motivation/communication with group members 1 Keep everyone updated on current goals/ ideas. Ask for progress ahead of the date when the deliverable are expected. ID Action to Minimize Risk 1 2 3 6 1 1 7 Lack of Equipment Delay Building Inaccurate Bill of Materials 1 1 1 Try to be as thorough as possible on the bill of materials so an accurate list of the materials can be made. 8 Poor Quality of Work Portray poor professionalism on the group as a whole Conflicting workloads 1 1 1 Hold weekly meetings to make sure everyone is on task and doing their share of the work Detailed Design Review MSD 1 5/3/2013
Likelihood scale Severity scale 1 - This cause is unlikely to happen 1 - The impact on the project is very minor. We will still meet deliverables on time and within budget, but it will cause extra work 2 - This cause could conceivably happen 2 - The impact on the project is noticeable. We will deliver reduced functionality, go over budget, or fail to meet some of our Engineering Specifications. 3 - This cause is very likely to happen 3 - The impact on the project is severe. We will not be able to deliver, or what we deliver will not meet the customer's needs. “Importance Score” (Likelihood x Severity) – use this to guide your preference for a risk management strategy Prevent Reduce Likelihood scale 1 - This cause is unlikely to happen Severity scale 1 - The impact on the project is very minor. We will still meet deliverables on time and within budget, but Action will be taken to prevent the cause(s) from occurring in the first place. it will cause extra work 2 - This cause could conceivably happen 2 - The impact on the project is noticeable. We will deliver reduced functionality, go over budget, or fail to meet some of our Engineering Specifications. Action will be taken to reduce the likelihood of the cause and/or the severity of the effect on the project, should the cause occur 3 - This cause is very likely to happen 3 - The impact on the project is severe. We will not be able to deliver, or what we deliver will not meet the customer's needs. Transfer Action will be taken to transfer the risk to something else. Insurance is an example of this. You purchase an insurance policy that contractually binds an insurance company to pay for your loss in the event of accident. This transfers the financial consequences of the accident to someone else. Your car is still a wreck, of course. Accept Low importance risks may not justify any action at all. If they happen, you simply accept the consequences. Detailed Design Review MSD 1 5/3/2013
