Southern Care Hospital (SCH) is a large, nonprofit regional hospital located in the southeast. Several years ago it contracted with the healthcare division of a major medical equipment supplier to provide Six Sigma train- ing to a group of its hospital employees. Since that time, numerous waves of Green Belts and Black Belts have been trained including people across all job ranks and repre- senting most departments. Green Belt training entails two weeks of formal in-class training while Black Belt training entails the two weeks of Green Belt training plus an addi- tional four weeks of training. Both Green Belt and Black Belt training require the completion of a Six Sigma project in addition to the in-class training.
One challenge currently facing SCH is significant lev- els of dissatisfaction from the medical staff regarding the three-day lead time it currently averages the nuclear medi- cine department to turn around the results of stress tests. In this case, lead time is defined as the elapsed time from when the stress test is ordered by a physician until the time when a radiologist from the nuclear medicine department signs off on the test results. Stress tests are used to deter- mine the amount of stress the heart can endure before either an abnormal rhythm or insufficien flow of blood to the heart develops. Typically, the stress test is administered by increasing the level of difficulty as a patient walks on a treadmill or rides a stationary bike. During the stress test vital statistics are collected and monitored, including the patients heart rate and blood pressure. Discussions with the medical staff indicate that they desire maximum lead times of a day and a half.
You have been selected to manage a Six Sigma project focusing on reducing the lead times associated with receiv- ing the results of stress tests. Based on your past experience with similar projects, you have identified 20 major activi- ties. SSHs steering committee has further granted you permission to select up to four team members from the available resource pool to staff the project.
Table 1 provides relevant background information on the 12 people currently available for assignment to a Six Sigma project. All resources are available to the project on
a part-time basis and therefore support Six Sigma projects in addition to performing their normal job assignments. The table lists the employee name, job title, level of educa- tion, years of work experience, Six Sigma rank (i.e., Green Belt or Black Belt), the number of Six Sigma projects the employee has worked on, the average amount of savings that resulted from the Six Sigma projects the employee has worked on, the employees hourly rate, and the percent of time the employee is available. The hourly rate represents what will be charged against your projects budget for work performed by a given employee. The percent available is based on a 40-hour work week. Therefore, the number of hours you can utilize a resource during a given week can- not exceed the available percentage times 40. To illustrate, Anna Frost can complete at most 8 hours (20% 40 hours/ week) of project work per week.
To facilitate project planning, SSH uses an advanced Six Sigma database program to track the progress and per- formance of all ongoing projects. Furthermore, the HR department has developed a process to estimate the profi- ciency of employees completing various planned tasks in future Six Sigma projects based on the historical data con- tained in the database. The proficiency numbers can range between zero and 100, with a zero indicating no ability to perform the task and 100 implying extensive expertise and experience performing the task. Table 2 summarizes this information for the 12 employees listed in Table 1 for the 20 project tasks initially identified. Past experience with these estimates indicates they are fairly accurate over an entire project but that employee performance typically varies ±3 percentage points within a given week. Thus, an employee with an estimated proficiency of 90 on a particu- lar task would be expected to perform in the 8793 range on the task in any given week.
A final comment regarding the available resources is in order. Specifically, past experience with projects indicates that conflict occasionally arises when more than one Black Belt is assigned to the same task. When such conflict does arise, it tends to negatively impact both the time required to complete tasks that the Black Belts are jointly assigned to as well as the overall quality of the work performed.
