The project is meeting all goals at this timeAaron2Fabrication and AssemblyMechanical deliverables are complete.

+AaronFirst, show them our working model!! Explain subsystem we showed them last time, then dive into all of the functions of each part. Dont pass around.Talk about issues poor cutting bit precision and improper press fits, making assembly harder. Forgotten tools, inability to quit with fiberglass, causing time to be wasted An example of a fairly simple part that was overlooked3Electrical Testing

These are major problems we have encountered, the problem tracking was used to close them out.

+LaurenAll problems are being tracked and progress is being madeAll electrical issues need to be trackedFor presentation, do a deep dive on one problem to show example of the process being used

10Problem Solving Product Cost of Purchased PartsLooked into finding cheaper ABS when material changedFound other materials at a lower costOverall was able to reduce cost of purchased parts to below the requirementProduct cost is more than $100 due to the change of material for some partsRequiring more ABS plastic to manufacture handle increased the price of the productFind a cheaper supplier for ABS plastic or find cheaper suppliers for the other parts of the handle and make sure quantity of parts is correct for 10,000 manufactured canesFind cheaper suppliers for parts and correct quantities for 10,000 manufactured canesFor 5 parts we were able to find the quantities that we need for a cheaper pricePrice of product is now $99.31, which meets our requirement of $100The Problem Solving Matrix enabled us to meet our requirements.+Lauren

11Risk CurveAll risks are being managed.+BJThis is the status of our risk curve as of now. Our actual # is 27 and we planned to be at 20 for the sum of the risks importance. The spike in the curve is due to the fact that we were able to think of some more risks that would negatively affect our project. We have completion dates associated with each risk so sticking to our plan, we should be on track to reduce all risks by May 4th

Will be resolved April 11th. +BJThis chart shows the risks that we have left. The most important risk is that PCB will not work correctly. BJ will be able to explain what effect this will have on our project and what our plans are to mitigate the risk.13Project BudgetMeeting our customer needs under the new budget.+JessThis is a summary graph of our project budget, we requested for an increased budget and thats what the red line represents.

Bring project plan to meetings, so that we are able to tell them exactly when we will be accomplishing deliverables

Make sure to control scope of project
