Explanation
The answer provided correctly defines a production system as a user of resources that transforms inputs into desired outputs. This definition highlights the purpose and function of a production system, which is to utilize resources effectively and efficiently to create the desired end products or services.

Explanation
The core services refer to the basic features or functions that customers expect to receive when they purchase a product. These are the fundamental services that fulfill the primary needs or requirements of the customers. Core services are essential for customer satisfaction and are considered the foundation of a product's value proposition. By providing these basic services, companies can meet the expectations of their customers and ensure that their products meet the desired standards.

Explanation
Value-Added Services refer to additional services or features provided by an organization that go beyond the basic product or service offering. These services are designed to enhance customer experience, provide added value, and set the organization apart from competitors. By offering unique and valuable services, the organization can build strong relationships with customers, creating loyalty and a positive association with the brand. This differentiation helps the organization stand out in the market and creates a competitive advantage.

Explanation
Order qualifiers are the minimum requirements that a product or service must meet in order to be considered by customers. These qualifiers are the basic criteria that allow a firm's products to be eligible for purchase. On the other hand, order winners are the factors that set a firm's products or services apart from its competitors. These are the criteria that differentiate one firm from another and ultimately influence customers to choose one firm's offerings over another.

Explanation
Productivity is a measure of how efficiently resources are being utilized. It is calculated by dividing the outputs by the inputs. This ratio provides an indication of how effectively resources are being transformed into desired outcomes. A higher productivity ratio indicates that resources are being used more efficiently, while a lower ratio suggests inefficiency in resource utilization. Therefore, productivity is a key metric used to assess the effectiveness and efficiency of an organization or individual in achieving their goals.

Explanation
The three measurements of productivity are total, partial, and multifactor. Total productivity measures the overall output of all inputs in a production process. Partial productivity focuses on the ratio of output to a single input, such as labor or capital. Multifactor productivity considers the ratio of output to a combination of inputs, including labor, capital, and other resources. These three measurements provide different perspectives on productivity and can be used to analyze and improve efficiency in different aspects of a business or production process.

Explanation
Efficiency refers to the ability to perform a task or activity in the most optimal and productive manner, ensuring that resources are utilized effectively. On the other hand, effectiveness is about achieving the desired results or outcomes, focusing on doing the right tasks that align with the goals and objectives. In other words, efficiency is related to the process, while effectiveness is related to the outcome.

Explanation
The capacity refers to the point in production where a firm's average costs start to increase. This typically occurs when a factor, such as labor or equipment, becomes fixed and cannot be easily increased. At this point, the firm may experience diminishing returns or inefficiencies in production, leading to higher costs per unit. Therefore, capacity is an important consideration for firms to optimize their production and manage costs effectively.

Explanation
Critical path refers to a sequence of activities that must be completed in order to finish a project on time. If any activity on the critical path is delayed, it will cause a delay in the overall project completion. On the other hand, slack refers to the amount of time an activity can be delayed without affecting the project's finish date. Activities that are not on the critical path have slack, as they can be delayed without causing a delay in the project. However, activities on the critical path have zero slack, meaning any delay in these activities will directly impact the project's finish date.

Explanation
The three organization structures mentioned are commonly used in businesses. A functional/process organization is based on departments or functions, where employees with similar skills or expertise are grouped together. A product organization is structured around specific products or services, with teams dedicated to each product line. A matrix organization combines elements of both functional and product structures, allowing employees to have dual reporting relationships. These structures help businesses to effectively allocate resources, streamline communication, and improve overall efficiency.

Explanation
The explanation provided in the answer accurately describes the difference between authority and power. Power refers to the ability to influence decisions, and it can exist regardless of one's position or formal control. On the other hand, authority is specifically tied to one's position and involves formal control and responsibility. This means that authority is granted based on the position one holds within an organization or hierarchy, while power can be derived from various sources and does not necessarily require a formal position.

Explanation
PERT stands for Program Evaluation and Review Technique. It is a project management tool that helps in planning and scheduling complex projects. PERT breaks down the project into activities and sub-activities, determines the precedence relationships between them, and estimates the time required to complete each activity. This allows project managers to create a realistic timeline and identify critical paths in order to effectively manage and control the project.

Explanation
The two types of CPM are single time estimate and three activity time estimates. The single time estimate is used when activity times are known with certainty and is used to determine timing estimates for the project, each activity in the project, and slack time for activities. On the other hand, three activity time estimates are used when activity times are uncertain and are used to obtain the same information as the single time estimate.

Explanation
The formula provided defines the concept of value as the ratio of positive aspects to the sum of negative aspects. This suggests that value is determined by weighing the positive attributes against the negative ones. The higher the ratio, the greater the value. This formula can be applied in various contexts, such as evaluating the worth of a product or assessing the benefits and drawbacks of a decision.

Explanation
The correct answer explains that company strategy includes elements such as mission, vision, goals/objectives/requirements for success, and guiding principles. SWOT stands for strength, weakness, opportunities, and threats, which are factors that are analyzed in the strategic planning process. These factors help a company understand its internal strengths and weaknesses, as well as external opportunities and threats in the market, allowing them to develop a strategy that leverages their strengths, addresses weaknesses, takes advantage of opportunities, and mitigates threats.

Explanation
Concurrent engineering refers to the process of developing project design functions simultaneously, with open and interactive communication among all team members. This approach aims to reduce the time required to bring a product to market, lower costs, and enhance the quality and reliability of the final outcome. By involving all team members from different disciplines in the early stages of design, potential issues can be identified and resolved more efficiently, leading to a more streamlined and successful project.

Explanation
The QFD (Quality Function Deployment) techniques involve a series of steps to ensure that customer requirements are effectively translated into measurable engineering requirements. The first step is to identify the customer and understand their needs. Then, the customer requirements are determined and prioritized based on their importance. Competition benchmarking is done to analyze the offerings of competitors and identify areas for improvement. The next step is to translate the customer requirements into specific and measurable engineering requirements. Finally, engineering targets are set to guide the design process and ensure that the final product meets the customer's needs.

Explanation
Value analysis (VA) and value engineering (VE) are processes used to analyze and improve the value of a product or service. VA involves evaluating the components and functions of a product or service to identify areas where costs can be reduced without sacrificing performance or quality. VE, on the other hand, focuses on redesigning or reengineering the product or service to achieve the same or better performance at a lower cost. Both VA and VE aim to optimize the value of a product or service by reducing costs while maintaining all functional requirements specified by the customer.

Explanation
VA, which stands for Value Analysis, is used to study various aspects such as products, processes, services, and builds. It evaluates the functions and interactions of these elements, challenges the specifications, and provides a comprehensive understanding of the problem at hand. Furthermore, VA often leads to potential cost reductions ranging from 25-35%. Therefore, VA is utilized to analyze and improve different aspects of a system or organization, leading to better efficiency and cost-effectiveness.

Explanation
The answer provided lists the five VA (Value Analysis) process phases, which are information, innovation, integration, evaluation, and implementation. These phases represent the steps involved in conducting a value analysis, which is a systematic approach to identify and improve the value of a product, service, or process. The information phase involves gathering data and understanding the current situation, while the innovation phase focuses on generating ideas and finding creative solutions. The integration phase involves selecting the best ideas and integrating them into a plan, followed by the evaluation phase to assess the feasibility and effectiveness of the plan. Finally, the implementation phase involves putting the plan into action and monitoring the results.

Explanation
DFMA stands for Design for Manufacturing and Assembly. It is a methodology that focuses on simplifying the design of a product in order to improve its manufacturability and ease of assembly. The greatest improvements related to DFMA come from reducing the number of separate parts in the product. By doing so, it becomes easier and more cost-effective to manufacture and assemble the product. This can lead to benefits such as reduced production time, lower costs, improved quality, and increased overall efficiency.

Explanation
Breakeven point refers to the point where the total cost or expenses incurred by a business are equal to the total revenue generated. At this point, there is no net loss or gain, and the business has "broken even". This means that the business has neither made a profit nor incurred a loss. In other words, the breakeven point is the level of sales or production at which the business covers all its costs without making any additional profit.
