Software Development Essentials: SDLC, SRS, COCOMO, Agile & Risk
Functional vs. Non-Functional Requirements
Understanding the difference between functional and non-functional requirements is crucial in software development:
- Functional Requirements: Specify what the system should do (features, actions, and behaviors).
- Non-Functional Requirements: Define how the system should perform (quality attributes like performance, security).
Here’s a comparison:
- Functional: Focuses on specific functionalities of the system.
- Non-Functional: Focuses on system quality and constraints.
Service Prototyping: Testing Design Concepts & Solutions
Topic 6: Prototyping
The objective of prototyping is to test the design concept, the service design, and their underlying new proposed ideas and solutions to approve or reject them. If they are approved, the process goes ahead. If they are not approved, then they should be amended, improved, and fine-tuned depending on the results of the prototype testing. Their ideas should be revised, etc.
What is Service Prototyping? Prototyping Goals
It is a lightweight simulation or sample version of the actual

Types of Internal Information
Internal information includes data contained within documents generated by a health center during its operations. We can distinguish two main types:
- Information on Logistics: This includes data in documents discussing the general operation of the facility (warehouse, accounting, etc.). These documents are managed by the Administrative Archives.
- Information Relating to Patient Care: This includes data in clinical and administrative documents related to direct patient care
Software Testing Techniques: White-Box, Model-Based, and More
Question 1: White-Box Testing
What is a key characteristic of white-box test techniques?
Answer: (b) They are used both to measure coverage and to design tests to increase coverage.
Question 3: Model-Based Testing
What is Model-Based Testing?
Model-Based Testing (MBT) is a software testing approach where test cases are derived from a model representing the system’s behavior, requirements, or processes.
Question 4: Pairwise & Neighborhood Integration
Pairwise Integration:
- A testing technique where
V-Model SDLC: Verification and Validation in Software Development
Understanding the V-Model in SDLC
The V-model is a type of SDLC (Software Development Life Cycle) model where the process executes in a sequential manner, forming a V-shape. It is also known as the Verification and Validation model. This model is based on the association of a testing phase for each corresponding development stage. Each development step is directly associated with a testing phase. The next phase starts only after the completion of the previous phase; for each development activity,

Functional Decomposition Diagrams (DDF)
Techniques to represent the decomposition of the functions of a system.
Its purpose is to represent the hierarchy of system processes at different levels of abstraction. It decomposes a high-level function into low-level functions.
They are used to represent other information such as company structure.
Types of DDF
- Functions of the system at different levels of abstraction but without considering the flows between them.
- The functions and input and output data
- Functions
