capacity to offer a vital analytical tool to adequately recognize if a process contains any defects Chase Jacobs amp Aquilano 2005 It additionally makes it easier to make a decision regarding any variation pertaining to quality control and its capacity to become more efficient The control chart Figure 11 contains the measurements of the first four weeks which have been plotted Figure 12 based on each day of the week and the amount of time it took to drive to work per the owchart Figure 13 Proper statistical analysis in combination with suitable planning offers valuable data in order to make appropriate decisions based on the pertinent data which was collected Planning is essential when it comes to the evaluation of such a process in order to reach the best possible outcome Chase et al2005 A possible eXplanation for the rationale behind the variation in the amount of time it takes to drive to work is due to the fact there is a hindrance pertaining to the driver39s capacity to drive directly to work If the driver has an adequate supply of gas then the automobile has the capacity to let the driver proceed to the final destination Nonetheless if there is not an adequate supply of gas the driver must drive to the closest gas station in order to obtain enough gas for the automobile to be able to drive to work Once the gas predicament is solved the remaining ow is practically free of potential bottlenecks The control chart for driving to work does not show major discrepancies except for the fourth week in which the driver had to obtain gas on the second day Tuesday There will certainly be additional discrepancies in the upcoming months due to eXpected seasonal factors which will slow down the process These factors primarily PROCESS IMPROVEMENT PLAN 3 include weather related issues It is known that in winter there is a rise in accidents and as such traffic will surely be more congested causing the process to take longer Additionally snowfall debilitates the stability of the roads which causes drivers to drive slower The same holds true in spring where the rate of precipitation is elevated causing it to rain more frequently As such there will additionally be more delays Summer months tend to be the most efficient as the weather is typically constant and pleasant The same holds true for a majority of the fall season There are ways in which these bottlenecks can be properly eliminated One possible method would involve shifting the process to a more eXpedient time in which the bottleneck may have excess capacity For example the driver could obtain gas prior to the ow even beginning at a time in which the gas station is much less occupied possibly at night In other words the amount of traffic at nighttime has less capacity to produce the transport of other vehicles which would make the process of obtaining gas much quicker This in turn would permit the driver to drive directly to work every morning without having to drive to a gas station during the ow The driver may additionally obtain gas on the weekend which would also permit the driver to drive directly to work although the process may take longer depending on the time of day The driver may additionally consider speeding up the other processes putting on seatbelt safely driving out of garage driving to work etc so as to reduce the potential bottleneck s capacity to slow down the overall ow When it comes to weather the driver may opt to leave for work at a less favorable time which would entail the capacity for less traffic both on the way to work and the way from work The driver may also consider purchasing seasonal tires which may cause the vehicle to function more effectively on the road and at the same time reduce the probability of PROCESS IMPROVEMENT PLAN 4 an accident occurring Additional add ons such as enhanced windshield wiper blades may also make the ow more efficient The control chart demonstrates the results of the data which was collected and can and will be used to identify analyze and hopefully improve the flow and at the same time apply the applicable control factors within the process Although only four weeks have been measured the data will be continually compiled in order to ensure quality and assist in the continuous improvement process The sample size utilized in the example is indeed small but it is certainly large enough to utilize in order to formulate an estimate of the population mean By observing and recording the measurements for a longer duration the mean would be better understood and as such the control limits may become modified Even though the process does not appear to be out of control long term data may show even more control and the standard deviation may be more realistic
