Concept explainers
Take a process that you encounter on a daily basis, such as the lunch cafeteria or the journey from your home to school or work, and identify the bottlenecks that limit the throughput of this process.
Interpretation: The barriers that hinder the process that is carried out regularly, i.e., a repeated process.
Concept Introduction: A bottleneck is the neck of a bottle, which restricts the flow of the liquid out of the bottle. In the case of process management, it refers to the sub-process and/or the activity which restricts the flow.
Answer to Problem 1DQ
Taking the process of getting ready for office and reaching the office:
- It is seen that preparing and eating breakfast is the constraint most of the time.
- At other times, driving to office becomes the constraint (due to allocated reasons).
Explanation of Solution
The process of getting ready for office and reaching the office is made up of many sub-processes/activities which can be sketched as follows:
In such a process, there is no tangible output but there is only one OUTCOME, that of reaching the office in time. The percent of times, the operator reaches in time is a measure of the efficiency of this process.
The outcome of reaching late may coincide with a longer time spent on preparing breakfast or longer time spent in driving.

- At Hewlett-Packard (HP), billions of dollars of product are being shipped - from computers and diagnostic devices to toner cartridges each year. Customer orders come in 24 hours a day, 365 days a year. Nearly 16,000 different products are requested daily and have to be shipped from six different warehouses which are located 30 or more miles apart. It often takes weeks to get the products into the customer’s hand. This is a serious problem if customers have contracts with HP stating deliveries are to be made in three (3) business days, or less. That means that from the time a customer calls the HP customer service line, they will have their replacement part and be back in operation within 72 hours or less, no matter where that customer is located. On average, delivery to customers takes 6+ days. It is imperative that HP guarantee for delivery of products and services are followed to protect their image, secure its position in the market place, increase its competitive advantage and its…arrow_forwardImplement the Graduate Student Admission process using the Bonita workflow management system.

The form is then handed back to the receptionist who enters the information into the computer system for the dentist to see. A dental assistant then takes an X-ray from the patient. A dentist then performs the checkup and discusses any issues with the patient. Based on conversations with staff members at the clinic, you have obtained the following information on the process: It takes about 5 minutes for a customer to fill out the paperwork. Entry of information on the paperwork into the system and verification with past records takes another 5 minutes for a receptionist. There are two receptionists.

Rami El‐Hussieny was the day shift operations manager, and, unfortunately, he did not know how to answer Elizabeth's question. What she wanted to know was simple enough: How many dozen rolls should be placed in the proofer in anticipation of the night's dinner business? The problem was that the frozen dinner roll dough used at the Sands Cafeteria needed to be proof for at least 2 hours prior to being baked for 15 minutes. If too many rolls were proofed, they would never be needed, but they would still have to be baked and made into bread dressing or even tossed out. If too few dozen were proofed and the night was busier than anticipated, they would run out of “Fresh Baked Rolls” (one of the restaurant's signature items), and Rami knew that the night manager would be really upset. It was a daily guess, and sometimes Rami missed the guess! He wondered if a prebaked roll with a shelf life…arrow_forward
