Introduction to the Smart School Attendance System
Unlock Audio Lesson
Today, we will discuss how we can apply problem scoping to design a Smart School Attendance System. Can anyone tell me what the first step in problem scoping is?
Isn't it defining the problem clearly?
Exactly! We need to understand what problem we are trying to solve. In this case study, the problem is manually marking attendance, which is time-consuming and error-prone. Let's dive deeper using the Four Ws. Who wants to start with the first W?
I can! The first W is 'Who.' The key stakeholders are the teachers, students, and school administration.
Great job! Remember, understanding who is affected by the problem is crucial for developing a relevant solution.
Understanding 'What' Needs Solving
Unlock Audio Lesson
Now, let’s discuss the second W: 'What.' What do we need to automate in the attendance system?
We need to automate the attendance recording part!
Correct! Automating attendance tracking will help ensure accuracy and save time. Can someone share why this automation is necessary or relevant?
It helps prevent misuse like proxy attendance, and also helps teachers manage their time better.
Excellent points! Understanding what we need to fix helps us focus our efforts. Let’s move to the next W.
Defining the Scope: Where and Why
Unlock Audio Lesson
Next, we consider the 'Where' aspect. Where does this problem exist?
In schools, right?
Exactly! And now, can anyone explain why resolving this issue is important?
Because it impacts a lot of students and teachers! If we can automate it, it makes it easier and more reliable.
Well said! Understanding the 'Why' is fundamental in securing buy-in from stakeholders. Overall, these Four Ws help us understand the entire problem structure.
Using the Problem Canvas
Unlock Audio Lesson
Now that we've outlined the Four Ws, let’s put this information into the Problem Canvas. What goes into the 'Problem Statement' section?
The problem is that manually marking attendance takes too much time.
Yes, excellent! And what about the 'Stakeholders' section?
It includes teachers, students, and school management.
Great! Filling out the Problem Canvas helps visualize and structure our findings and can aid the AI development process.

Quick Overview
Standard
The Smart School Attendance System case study demonstrates the identification and analysis of a problem related to manual attendance tracking in schools. It utilizes the Four Ws method and Problem Canvas to clarify stakeholder involvement, benefits, constraints, and success metrics essential for developing an efficient AI solution.
Detailed
Detailed Summary
The Smart School Attendance System case study focuses on the problem of manually marking attendance in schools, which is inefficient and prone to errors. The key components of problem scoping are applied here using the Four Ws methodology:
- Who: Identification of stakeholders includes teachers, students, and school administration who directly interact with the attendance system.
- What: The specific problem is the need to automate attendance tracking in schools to enhance accuracy and efficiency.
- Where: This problem is prevalent in school environments, highlighting the localized nature of the issue.
- Why: The importance of solving this problem is emphasized by the need for improved accuracy, time-saving measures, and prevention of proxy attendance.
Additionally, the Problem Canvas summarizes key aspects:
- Stakeholders: Teachers, students, school management
- Benefits: Time-saving, increased accuracy, reduced incidences of proxy attendance
- Constraints: Factors such as budget limitations and the availability of facial recognition technologies
- Success Criteria: Success is measured by achieving a face recognition accuracy of over 95% and ensuring the system is used daily.
This case study exemplifies how structured problem scoping leads to effective AI solutions, ensuring that crucial factors are carefully considered before development.

Problem Statement

Manually marking attendance in schools is time-consuming and can be prone to errors or proxy attendance.
Detailed Explanation
The problem statement outlines the main issue with the current method of taking attendance in schools, which is done manually. This approach is not only slow but also susceptible to mistakes, such as incorrectly marking students present when they are not, or allowing someone to sign in for another student (proxy attendance). These issues can negatively affect record-keeping and accountability in schools.
Examples & Analogies
Imagine a teacher having to call out names and waiting for students to respond one by one to check attendance. This process can take too much time, especially in large classes. Additionally, think of a scenario where a student asks a friend to mark them present while they are not in class, leading to false records. Such issues highlight the need for an automated system.
Using the Four Ws

• Who: Teachers, students, school administration.
• What: Need to automate attendance.
• Where: In schools.
• Why: To save time, ensure accuracy, and prevent misuse.
Detailed Explanation
The Four Ws framework allows us to dissect and understand the problem better. 'Who' identifies the primary stakeholders affected by the problem: teachers who take attendance, students who are being marked, and the school administration overseeing the processes. 'What' specifies the issue at hand, which is the need to automate attendance. 'Where' addresses the location, confirming that schools are the focus. 'Why' explains the importance of finding a solution—mainly to save time for teachers, increase accuracy in attendance records, and prevent fraudulent activities like proxy attendance.
Examples & Analogies
Consider a factory that also has to keep track of employee attendance manually. If a manager or HR representative were to use the Four Ws to analyze problems with attendance tracking, they would similarly identify employees (who), the need for accuracy in records (what), the factory environment (where), and the time-saving benefits of automation (why).

• Stakeholders: Teachers, Students, School Management
• Benefits: Time-saving, accuracy, reduced proxy
• Constraints: Budget, availability of facial recognition data
• Success Criteria: 95%+ accurate face recognition, daily usage.
Detailed Explanation
The Problem Canvas serves as a comprehensive tool to summarize the critical elements of the project. The stakeholders include teachers, students, and school management who will directly benefit from an automated attendance system. Key benefits highlighted are the time saved during attendance marking, the improved accuracy of attendance records, and the reduction of proxy attendance attempts. However, constraints such as budget limitations and the availability of facial recognition data must be considered in the project plan. Finally, the success criteria provided, such as achieving over 95% accuracy in face recognition and ensuring daily usage, set a clear benchmark for when the project can be considered successful.
Examples & Analogies
Think of a school gym that wants to implement a new entry system that scans student IDs. In the Problem Canvas for this project, the stakeholders would be the gym staff and entering students (who), the benefits would be preventing unauthorized access (benefits), the cost of the scanning technology (constraints), and the low likelihood of false positives (success criteria). This process outlines what is necessary for success.
