Supply Chain Management
Identify the benefits of a functional/departmental layout
- A problem occurring at a single workstation does not usually stop production. - It offers many different routes for a given job.
Identify the drawbacks of a functional layout
- A significant amount of time is usually needed to clean & setup workstations. - Materials handling costs are high when jobs are moved from department to department. - Processing times & work-in-process inventory tend to be high.
Identify the differences between the DFSS (design for Six Sigma) and the DMAIC (define, measure, analyze, improve, control) processes.
- DFSS makes use of design engineering tools, whereas DMAIC ideally works with actual products & operational data. - DFSS takes places in the developmental phase, whereas DMAIC takes place after a new product has been launched.
Identify the characteristics of 3D printing when comparted to traditional manufacturing processes
- It can be made close to the customer, reducing inventory and transportation. - It is highly flexible. - It eliminates the need for producing parts and assembly by printing products in one piece. - It uses relatively low-cost equipment.
Regarding standard deviation:
- It is an indicator of process variability. - A low standard deviation indicates that the data points tend to be very close to the same value, typically the mean. - A high standard deviation indicated that the data are spread out over a large range of values.
Identify the process characteristics of a job shop type of process
- Job sequencing is challenging. - High work-in-process inventory in necessary. - High variety of inputs & process flows are necessary.
Regarding Kaizen Improvement:
- Kaizen is also known as continuous improvement. - Pursuit of small improvements keeps people thinking about the process & its current operation. - It states that the long-term success of an organization occurs only when everyone in the firm identifies & implements improvements daily.
Identify the decisions and activities made by a manufacturing and service operations manager that have potential impact on the product quality
- Management of facilities & equipment - Scheduling of work - Design of work policies - Design & e
Identify the characteristics of a repetitive process
- Operations managers tend to focus on developing standard methods & procedures to continuously improve quality & reduce costs. - Products made using a repetitive process are typically made to stock. - Discrete products flow through the same sequence of activities, & equipment can be specialize to each specific task.
Identify the true statements about cellular manufacturing
- Processing time, inventory, material flow distance, & setup times are reduced. It can increase the flexibility of repetitive processes. - Cells can make job shops or batch processes more efficient.
Regarding quality problems that arise in Total Quality Management (TQM):
- Quality problems are often only solvable through the involvement of suppliers. Problem prevention is emphasized in TQM, rather than fixing problems after they occur. Problem solving is most effective when decisions are based on the analysis of actual data.
Regarding a product layout:
- Repetitive & Continuous process usually use a product layout. - Lack of flexibility & low variety for employees are drawbacks. - The flow of products or customers is visible & easy to trace.
Identify the characteristics of a batch process
- Some common inputs - Dominant flow patterns - High setup time
Identify the variations in repeated activities that are often the major sources of problems in operations processes.
- Variations in a purchased material characteristic. - Variations in marketing promotions. - Variability in the time taken to complete a task.
Identify the values that characterize Total Quality Management (TQM)
- employee empowerment - extended process view of operations - emphasis of customer requirements
The different expenses that a carrying cost encompasses are:
- insurance - taxes - cost of owning & maintaining storage space - cost of materials handling, tracking, & management - cost of obsolescence, loss, & disposal - opportunity cost
Identify the categories of inventory performance metrics that address the issues of asset productivity
- inventory turnover - days of supply
Outcomes of the bullwhip effect
- it results in increased costs. - it incites excessive expediting. - it introduces uneven levels of capacity utilization. - it causes increased levels of inventory.
Advantages a company enjoys due to high inventory turnover rate
- less risk of obsolescence - decreased expenses - lower asset investment - increased sales volume
Regarding cycle stocks:
- the primary driver of cycle stock is the order quantity. - one way to reduce the total average inventory is to reduce the order quantity. offering the lowest possible price per unit regardless of order quantity would result in smaller order quantities.
Factors that often affect the success of TQM
- trust between labor & management - strong, charismatic leadership - crisis situation or compelling reason for change
