L4M7 CHAPTER 3 Flashcards
What is scheduled maintenance?
Scheduled maintenance is any repair and upkeep work performed within a set timeframe. It details when given maintenance tasks are performed and by whom. Scheduled maintenance may occur at repeating intervals or in response to a work request.
The following are examples of scheduled maintenance except…
“Repair signage damage from a recent storm”
Scheduled maintenance is any repair and upkeep work performed within a set timeframe. It details when given maintenance tasks are performed and by whom. Scheduled maintenance may occur at repeating intervals or in response to a work request.
Assuming that all other factors are constant except one, the net present value of a capital expenditure increases when…?
“Net cash flow during a time period increases”
Net present value (NPV) is the ‘today’ net value that deprives from ‘future’ cash flow of an investment or a capital purchase.
The net present value increases when the numerators (net cash flows) increase and/or denominators (1+i-period) decrease.
Which of the following correctly describes the triple bottom line?
Triple bottom line is a sustainability framework that examines a company’s social, environment, and economic impact (or People, Planet, Profit).
A major investment bank is planning to purchase a complex banking system that will interface with multiple applications at varying times of the day. Before deploying the system, there are various levels of testing that must be performed through joint testing between the in-house team and the off-shore testing consultants. The testing will be performed in a resource-constrained shared environment and managed by the on-shore development team. The costs for testing are generally classified as…?
Acquisition Costs.
The buying organisation (investment bank) must conduct various types of testing before the deployment of the software system. These tests can be functional testing, factory acceptance testing and/or user acceptance testing. The costs for all these types of testing are classified as acquisition costs with regards of total cost of ownership.
ASI Ltd is known for its commitment to sustainability. ASI builds railroad ties and pilings using recycled plastic bottles and industrial waste instead of standard materials such as wood, steel, and cement. This practice helps the company save 15% in comparison with traditional material purchases. Which pillar of sustainability would include the practice of ASI Ltd?
The triple bottom line is a sustainability framework that examines a company’s social, environment, and economic impact (or People, Planet, Profit). ASI Ltd practice would reduce the waste into the environment as well as keep the business more profitable.
A brewery sells its beer in aluminum cans. It recycles the cans by using contractors to collect and mold the used cans. This is an example of…?
Closed loop recycling.
There are two main processes of recycling – open loop recycling and closed loop recycling.
Closed loop recycling is focused on resource sustainability, which means that recycling of a material can be done indefinitely without degradation of properties. In this case, conversion of the used product back to raw material allows repeated making of the same product, which helps hazardous waste generators reduce carbon footprint and achieve corporate sustainability initiatives.
Closed-loop recycling is common in specialized industries, such as the computer and battery industries, which use expensive or complex goods that cannot easily be broken down post-consumption into constituent materials.
A prime example of a closed-loop recycling process is the recycling of aluminum cans. Aluminum can be recycled to form new cans with little material degradation or waste creation.
Open Loop Recycling
Open loop recycling is a method that delays disposal by converting manufactured goods and spent materials into both new raw materials, which can be used for a manufacturing purpose, as a fuel source for a different manufacturing process and waste products.
Typically, materials recycled through open-loop recycling will be used for purposes different from their original purpose.
This means that the input into the recycling process is converted to a new raw material, which can be used as an input into another manufacturing process.
Materials in an open loop recycling process are treated using various forms of treatment including heat, chemical reactions, or physical crushing.
An organisation always obtains a negative cash flow regarding removal and disposal of assets. Is this statement true?
“No, the organisation may recover the value of the assets by reselling it”.
Explanation
Assets in their end of life need to be removed or disposed. Though an organisation can incur some costs in decommissioning or removal of the assets, it may recover costs by reselling the assets. Therefore, sometimes the organisation can gain positive cash flow from removal and disposal of assets.
A hospital is purchasing a new software product that will advise nurses when to give medications to hospitalised patients. This is a mobile application that will be used on tablets carried by the nurses. The software is being developed and tested by a company that specialises in mobile medical applications. This software will interface with existing hospital software that orders the medications from the pharmacy. Which acceptance test activity will be required to check whether the new software integrates well with current IT system?
Compatibility testing would be the most appropriate test.
The requirements for the new software is that it will interface with the current system.
There are also other acceptance tests
Health and safety test aims at establishing new health and safety routines, providing guidance notices and documentation and ensuring designed-in safety in operation.
Stress testing (sometimes called torture testing) is a form of deliberately intense or thorough testing used to determine the stability of a given system, critical infrastructure or entity. It involves testing beyond normal operational capacity, often to a breaking point, in order to observe the results.
A dry run (or a practice run) is a testing process where the effects of a possible failure are intentionally mitigated. For example, an aerospace company may conduct a “dry run” test of a jet’s new pilot ejection seat while the jet is parked on the ground, rather than while it is in flight.
The usage of “dry run” in acceptance procedures (for example in the so-called FAT = factory acceptance testing) is meant as following: the factory – which is a subcontractor – must perform a complete test of the system it has to deliver before the actual acceptance by customer.
Which are the key elements of total productive maintenance?
Quality maintenance & Autonomous maintenance.
Total productive maintenance (TPM) is an innovative concept in the manufacturing industry that evolved from the idea of preventive maintenance to adopt practices of productive maintenance, maintenance prevention, and reliability Engineering. What we now refer to as TPM, has become an ingenious approach to achieve overall equipment effectiveness by involving the workforce behind the machines (i.e. the operators).
8 pillars of TPM
1) 5S - Sort, straighten, shine, standardize, and sustain
Just like a physical structure starts with a grounded framework, building a strong TPM process requires a strong foundation in the form of the principles of 5S. This is a workplace organization method that is simplified into 5 basic steps:
Sort tools, equipment, and materials to identify which of these can be discarded
Straighten and set things in proper order to reduce unnecessary motion and efficiently travel between working groups and locations
Shine refers to performing necessary housekeeping to clean up the work area
Standardize and schedule activities to systematically form the habits to keep the workplace organized
Sustain the process and principles for long-term applications
The 5S approach provides a systematic approach to cleaning the workplace, thereby uncovering underlying problems and challenges.
2) Autonomous maintenance
Maintenance tasks and caring for equipment should start with the people using the equipment. The empowerment of operators to work on small maintenance tasks effectively allows the maintenance teams to focus on more specialized assignments.
3) Continuous improvement
Also known as the Japanese term Kaizen, Continuous Improvement promotes the attitude of progressing towards zero losses and zero defects. Through small but continual tweaks to processes, the overall effectiveness and efficiency of the organization is developed.
4) Planned maintenance
Planned maintenance activities are essential to the prevention of equipment breakdown. Planned maintenance is performed by periodically evaluating the condition of equipment to proactively prevent deterioration and mechanical failures.
5) Quality maintenance
To ensure the satisfaction of the customer, manufacturing processes aim for zero-defect production. Standards for superior quality, and checks on whether the standards are being met, should be in place. The goal of quality maintenance is to identify any possible causes of deviations from zero-defect production.
6) Training
The idea of TPM is that everyone does their part to contribute to the overall productivity of the production process. In order to achieve optimum performance, and to build each member’s competence, proper training is required to equip each one with the theoretical and practical know-how of working with machines and equipment.
7) Office TPM
A key role that is often overlooked is the administrative department that works behind the scenes. Like the rest of the production teams and processes, the management and administrative functions are also subject to productivity improvement. This includes identifying and eliminating losses, and contributing to the overall performance of the plant.
8) Safety, health, and environment
The last of the eight pillars focuses on creating a safe workplace. The essence of this pillar is realized when actively applied to each of the other pillars. The successful implementation of this pillar will contribute to a secure and hazard-free workplace.
Which costs are categorised as operation costs in the total cost of ownership model?
Costs of any person who operates the equipment
Costs of consumables
In the Appendix A of a long-term supply contract of Bulk Drug Substance, both parties agree that “The reference price for Bulk Product at the specification, per gram, shall be US$10. The unit price for Bulk Product for a specific Purchase Order shall be computed by multiplying the above- specified reference price by two corrective factors, namely inflation correction factor and exchange rate correction factor”. This pricing appendix is an example of…?
Variable pricing or Adjustable prices mechanism using published sources on inflation rate and exchange rate.
Price setting mechanisms fall into two main categories: fixed and variable.
A fixed price mechanism is a straightforward concept which typically results in a relatively stable budget that can be forecast.
Variable mechanisms have an element of variable pricing per unit bought.
Setting a fixed price mechanism is in theory a relatively simple and straightforward concept, where the collector and the buyer agree on a fixed price for a specific material or mix of materials, for a certain length of time.
All other pricing mechanisms that are not fixed have an element of variable pricing per unit bought.
The most common variable pricing mechanisms can be divided into two groups:
- Where the benefit accruing to the buyer from acquiring the material is used to calculate what the payment to the seller should be; or Approaches to Materials Sales: A guide for local authorities
- Where the price paid is indexed to a published source of market price information.
What are the tools for reducing acquisition costs in purchasing?
Buyer discretionary spend 'User buying' Vendor managed inventory (VMI) Two-bin Kanban Product catalogue e-Procurement techniques, including some systems such as ERP, procure-to-pay (P2P), e-requisition, e-tendering, etc. Procurement cards
Decommissioning, removal and disposal of assets may have an impact on the environment. An organisation should have policies and procedures in place to enhance its environmental performance. Which standard family provides the guidance on environmental policies and procedures?
The ISO 14000 family. ISO 14001 provides requirements with guidance for use that relate to environmental systems. Other standards in the family focus on specific approaches such as audits, communications, labelling and life cycle analysis, as well as environmental challenges such as climate change.
ISO 27000 family of standards concerns information technology, with the goal of improving security and protecting company assets. Started in 2005, the two most popular standards are ISO 27001:2013 and 27002:2013. 27001 is management-based system, whereas 27002 is a technical document, focused on the individual and putting a code of conduct in place. Organizations can choose either standard; ISO 27001 has over 22,000 certifications worldwide. It is a broad standard, and for this reason the certification can be customized to fit the needs of the organization, and is not mandatory.
ISO 22000 sets out the requirements for a food safety management system and can be certified to it. It maps out what an organization needs to do to demonstrate its ability to control food safety hazards in order to ensure that food is safe. It can be used by any organization regardless of its size or position in the food chain.
ISO 9001 is a family of quality management standards, there are fourteen in total. Of these, ISO 9001:2015 is the only one that can be certified to. It was first published in 1987, and has since been updated about every 7 years. The standard details how to put a Quality Management System (QMS) in place to better prepare your organization to produce quality products and services. It is customer focused, and places an emphasis on continuous improvement and top management processes that extended throughout the organization.
A restaurant needs to buy a new freezer. The owner applies the total cost of ownership model to calculate the life-time cost of the freezer. This equipment has a price tag of $1,000, the supplier can offer free delivery if the restaurant pays off immediately. Estimated electricity consumption of the freezer is $200 in 5 years. The supplier ascertains that the freezer is very durable, buyer doesn’t need to care about maintenance costs. However, if the restaurant needs better protection from breakdowns, the warranty is free for the first 12 months after the purchase. This warranty package can be extended once for another 24-month period with the cost of $75. After 5 years, the buyer will be able to resell this freezer for $250. What would be the estimated total cost of ownership of this freezer if the restaurant owner buys the extended warranty package?
The total cost of ownership is $1,025.
The total cost of ownership would be the sum of all estimated costs.
The costs are as the following:
- Purchase price: $1,000
- Electricity consumption: $200
- Extended warranty: $75
Total expense = $1,000 + $200 +$75 = $1,275. Then subtract the resale price from this sum. The total cost of ownership is $1,025.
