Question 1

Exhibit https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/PeopleCert_CABA/page_139_img_1.jpg The diagram is what type of chart?

Accepted Answer

D

Explanation: The diagram is a classic example of a Control Chart. This chart is a fundamental tool in statistical process control (SPC) used to monitor a process over time. It features a central line representing the process average (mean), an upper control limit (UCL), and a lower control limit (LCL). Data points are plotted in chronological order. The primary purpose of a control chart is to distinguish between common cause variation (the natural, inherent variability of a process) and special cause variation (resulting from external, assignable factors). By observing patterns and points outside the control limits, analysts can determine if a process is stable and predictable.

Question 2

Which Conflict Management Strategy is also referred to as 'Strategy of Integration'?

Accepted Answer

B

Explanation: The Problem Solving strategy, also known as collaborating, is frequently referred to as the 'Strategy of Integration'. This approach is characterized by a high degree of both assertiveness and cooperativeness, creating a "win-win" scenario. It involves parties openly discussing their differences, exploring the root causes of the conflict, and working together to find a novel solution that fully integrates their respective insights and concerns. The goal is not just to find a middle ground but to synthesize different viewpoints into a superior, mutually beneficial outcome that satisfies everyone involved.

Question 3

A wide variety of activities which contribute nothing to the accomplishment of the objectives are termed as _________ by the management theorists.

Accepted Answer

B

Explanation: In management theory, particularly concepts derived from systems thinking and information theory, activities that consume resources but add no value to the final objective are metaphorically termed "noise." This term is used because, like static in a communication channel, these non-value-adding activities interfere with and obscure the "signal," which represents the core, value-creating processes. The goal of process improvement methodologies like Lean is to identify and eliminate this "noise" or "waste" to enhance efficiency, clarity, and overall effectiveness in achieving organizational goals.

Question 4

Which Use Case model convention is used to insert another Use Case that defines an alternative path?

Accepted Answer

B

Explanation: The > relationship is the standard UML convention used to model optional behavior or alternative paths for a Use Case. The extending Use Case adds functionality to the base Use Case only when specific conditions are met at a designated "extension point." This allows the base Use Case to be complete on its own, while the > relationship introduces a conditional flow that is not executed every time the base Use Case is performed. This directly corresponds to defining an alternative path.

Question 5

Which of the following statements best characterizes the Quality Management practice called Benchmarking?

Accepted Answer

B

Explanation: Benchmarking is a core quality management practice that involves the systematic comparison of a project's or organization's planned practices, processes, and performance metrics against those of other comparable projects or organizations. The primary purpose is to identify internal opportunities for improvement by studying "best-in-class" examples. This comparative analysis helps in setting realistic performance goals, adopting proven successful practices, and ultimately enhancing quality and efficiency. It is a proactive tool used in quality planning to learn from the successes and failures of others.

Question 6

The “Cause and Effect Diagram” is used to:

Accepted Answer

B

Explanation: The Cause and Effect Diagram, also known as an Ishikawa or fishbone diagram, is a fundamental quality management and business analysis tool. Its primary purpose is to structure a brainstorming session to systematically identify and categorize the potential causes of a specific problem (the "effect"). By organizing potential causes into distinct categories (e.g., People, Process, Materials, Equipment), it facilitates a thorough investigation to uncover the fundamental reasons for an issue, which is the core activity of root cause analysis (RCA). The diagram helps teams move beyond symptoms to identify the underlying problems that need to be addressed.

Question 7

Quality Assurance is defined as those activities which are designed to prevent defects. Which of the following is an example of Quality Assurance?

Accepted Answer

C

Explanation: Quality Assurance (QA) is a proactive, process-oriented set of activities aimed at preventing defects from occurring in the first place. Performing root cause analysis on systemic process errors is a core QA function. It involves investigating the fundamental reasons for defects to improve the development process itself, thereby preventing future defects. This directly aligns with the definition of QA as a preventative measure, as it focuses on fixing the process, not just finding faults in the product.

Question 8

In the EVM concept, a SPI greater than 1 indicates:

Accepted Answer

C

Explanation: The Schedule Performance Index (SPI) is a key metric in Earned Value Management (EVM) used to measure schedule efficiency. It is calculated by the formula SPI = EV / PV, where EV is the Earned Value (the value of work actually completed) and PV is the Planned Value (the value of work scheduled to be completed). An SPI value greater than 1 indicates that the project has completed more work than was planned for the period (EV > PV). This signifies that the project is ahead of schedule. Therefore, the team has used less than the planned time (100% or less) to accomplish the scheduled work, demonstrating favorable schedule performance.

Question 9

Which of the following is NOT a contribution by Walter Shewhart?

Accepted Answer

C

Explanation: Walter A. Shewhart is renowned as the "father of statistical quality control." His primary contributions include the development of Statistical Process Control (SPC) and the control chart, which are foundational to modern quality management. He also introduced the "Shewhart Cycle" (Plan-Do-Study-Act), a model for continuous improvement later popularized by W. Edwards Deming as the PDCA cycle. The Pareto Principle, also known as the 80/20 rule, was an observation by Italian economist Vilfredo Pareto regarding wealth distribution. It was later applied to quality control by Joseph M. Juran, who termed it the principle of the "vital few and trivial many." It is not a contribution of Walter Shewhart.

Question 10

Which inspection approach is based on sampling of work products and/or specifications?

Accepted Answer

B

Explanation: Agile Specification Quality Control (ASQC) is a formal inspection method adapted for agile environments that uses statistical sampling. Instead of reviewing 100% of the specifications, which can be time-consuming, a statistically valid sample of work products (like user stories) is selected for detailed inspection. The defect rate found in the sample is used to estimate the quality of the entire set. This approach provides a quantitative measure of quality while aligning with agile principles of speed and efficiency, allowing teams to decide if the batch of specifications is ready for development or requires further refinement.

Question 11

Business requirements are also called Non-Functional Requirements.

Accepted Answer

B

Explanation: The statement is false. Business requirements and non-functional requirements are distinct and separate categories in the requirements classification schema. Business requirements are high-level statements of goals, objectives, and outcomes that describe why a change has been initiated. They articulate the value the organization wants to achieve. In contrast, non-functional requirements (also known as quality of service requirements) describe the conditions under which a solution must remain effective or the qualities it must possess. They define how well the system should perform its functions, covering aspects like performance, security, usability, and reliability. They are a sub-category of solution requirements, which are derived from business requirements.

Question 12

_______________defects are more expensive to correct when found during the UAT phase than during other phases.

Accepted Answer

A

Explanation: The cost to fix a defect increases exponentially the later it is discovered in the software development lifecycle. Defects originating in the Requirements Phase represent fundamental misunderstandings or omissions of business needs. If such a defect is not found until User Acceptance Testing (UAT), the incorrect requirement has been designed, coded, and tested throughout the entire process. Correcting it requires extensive rework across all preceding phases, making it significantly more expensive to fix than defects introduced during design or coding. This principle is often referred to as the "cost of change" curve.

Question 13

Force Field Analysis is a structured approach for identifying and evaluating the forces that will promote, encourage, and support change and those that will resist change.

Accepted Answer

A

Explanation: The statement provides an accurate definition of Force Field Analysis. Developed by social psychologist Kurt Lewin, this model is a foundational tool in change management. It is used to understand the dynamics of a proposed change by identifying and evaluating the two opposing sets of forces. 'Driving forces' are those that promote, encourage, or push for the change, while 'restraining forces' are those that hinder, resist, or block the change. The analysis helps in strategizing how to strengthen the driving forces and/or weaken the restraining forces to successfully implement the change.

Question 14

The success of a software project developed using an adhoc development approach relies heavily on the:

Accepted Answer

C

Explanation: An ad-hoc development approach, often termed the "code-and-fix" model, lacks formal processes, structured planning, and comprehensive documentation. In this unstructured environment, there are no detailed requirements or design specifications to guide the team. Consequently, the project's success or failure is almost entirely contingent on the technical proficiency, experience, problem-solving skills, and informal communication of the individual team members. The team must compensate for the absence of a defined methodology through their personal expertise and "heroics" to deliver a functional product.

Question 15

A Context Diagram:

Accepted Answer

B

Explanation: A Context Diagram is the highest-level view in a set of Data Flow Diagrams (DFDs), formally designated as Level 0. It represents the entire system as a single process, showing its inputs and outputs from external entities. As it is the starting point and the first diagram created when modeling a system using this technique, it represents the initial, most abstract level. From this diagram, more detailed diagrams (Level 1, Level 2, etc.) are decomposed. Therefore, among the given choices, "First Level of DFD" is the most fitting description, interpreting "first" as the top-most or initial diagram in the hierarchy.
