TDD
TDD (Test-Driven Development) is a software development methodology where developers write automated tests before writing the actual code. It follows a cycle of writing a failing test, implementing minimal code to pass the test, and then refactoring the code while keeping tests green. This approach ensures code reliability, reduces bugs, and promotes clean, maintainable designs.
Also known as: Test-Driven Development, Test First Development, Red-Green-Refactor, TDD methodology, Test Driven
🧊Why learn TDD?
Developers should use TDD when building critical or complex systems where reliability and maintainability are priorities, such as in financial applications, healthcare software, or large-scale enterprise projects. It helps catch defects early, reduces debugging time, and encourages modular, testable code, making it ideal for agile teams and continuous integration environments.

2D cell culture is a laboratory technique where cells are grown as a monolayer on a flat, two-dimensional surface, typically in flasks, dishes, or plates. It is a fundamental method in biological and biomedical research for studying cell behavior, drug testing, and basic cellular processes under controlled conditions. This approach allows for easy observation, manipulation, and high-throughput screening of cells in vitro.
2D Design Review
2D Design Review is a collaborative process used in engineering, architecture, and product development to evaluate and refine two-dimensional design documents, such as technical drawings, schematics, or layouts, before implementation. It involves stakeholders examining these designs for errors, compliance with specifications, and feasibility, often using tools like CAD software or printed blueprints. The goal is to identify issues early, reduce rework, and ensure alignment with project requirements.
2D Drawing Coordination
2D Drawing Coordination is a process in engineering, architecture, and construction that involves managing and aligning multiple 2D technical drawings (such as floor plans, elevations, and sections) to ensure consistency, accuracy, and clash-free integration across different disciplines. It focuses on resolving conflicts, verifying dimensions, and maintaining design intent through systematic review and revision of drawings. This methodology is critical for preventing errors during construction and ensuring that all project stakeholders work from a unified set of documents.
360 Degree Feedback
360 Degree Feedback is a performance evaluation methodology where an employee receives confidential, anonymous feedback from people who work around them, including peers, subordinates, supervisors, and sometimes external stakeholders like clients. It provides a comprehensive view of an individual's skills, behaviors, and performance from multiple perspectives, helping identify strengths and areas for development. This process is often used in organizational development, leadership training, and performance management to foster self-awareness and professional growth.

3D Cell Culture
3D cell culture is a laboratory technique for growing cells in three-dimensional structures that more accurately mimic the in vivo environment compared to traditional 2D monolayer cultures. It involves using scaffolds, hydrogels, or specialized plates to create complex tissue-like models for biological research. This methodology is crucial in fields like cancer biology, drug discovery, and regenerative medicine for studying cell behavior, disease mechanisms, and therapeutic responses.
