Management Fundamentals: Theories, Skills, and Processes
Management: Art, Science, Roles, and Skills
Management is both an art and a science. As a science, management involves applying theoretical frameworks, principles, and techniques to manage organizations. As an art, management requires creativity, intuition, and experience to make decisions and lead people.
Managerial Roles (Mintzberg’s Classification)
- Interpersonal Roles:
- Figurehead: Representing the organization.
- Leader: Motivating and directing employees.
- Liaison: Building and maintaining relationships.
Strategic Management Frameworks and Core Concepts
Module 1: Strategy and Business Models
| Concept | Key Definition | Levels & Frameworks |
| Strategy | The long-term direction of an organization to achieve Competitive Advantage (doing things differently). | 3 Levels: 1. Corporate (Scope). 2. Business (How to compete). 3. Functional (Execution). |
| Strategy Statement | Vision (The Future), Values (Core principles that do not change), Objectives (Specific targets). | 3 Steps: Understand to Decide to Execute. |
| Business Model | Explains how a firm creates, delivers, and captures |
Geological Structures and Rock Classifications
Folds: Bending of Rock Layers
Folds are wave-like undulations in rock strata. They are most common in sedimentary rocks.
Origin and Mechanism of Folds
Folds originate primarily due to Compressional Stress. When rocks are pushed together, they shorten and thicken.
Ductile Deformation: Folds form deep within the crust where high temperature and pressure allow rocks to bend without breaking.
Tectonic Forces: Major fold belts (like the Himalayas) originate from the collision of tectonic plates.

Comparative Education Systems and Social Inequality
Education systems reflect cultural ideas about who should have access to education and why. The historical development of education in Spain, the UK, and the USA shows different views regarding access, poverty, social responsibility, and inclusion versus exclusion.
Inequality in the UK Education System
In the UK, education was first mainly for the upper classes. Grammar and public schools prepared wealthy children for leadership, while working-class

Generic Software Framework and Process Flows
A generic software framework consists of five core framework activities: communication, planning, modeling, construction, and deployment. These are supported by umbrella activities, including project tracking and controlling, risk management, quality assurance, and technical reviews.
The process flow describes how these activities are organized. Common flows include:
- Linear flow: Sequential execution of activities.
- Iterative process flow: Repeating activities
EU Transformation: Financial Crises, Brexit, and Policy Responses
Major Crises and Policy Shifts in the European Union
The Great Financial Crisis of 2008
The Great Financial Crisis of 2008 exposed deep structural flaws in the European and global financial systems. These flaws were rooted in decades of financial deregulation, excessive risk-taking, and weak supervision. Within the Eurozone, the combination of full capital mobility, centralized monetary policy under the ECB, and nationally regulated banking systems created major imbalances, resulting in capital flowing

The Neolithic Revolution: Agricultural Transformation
The Agricultural Revolution, also known as the Neolithic Revolution, marks the major transformation when early humans shifted from a nomadic, hunting–gathering life to settled agriculture. This process began around 10,000 BCE in different parts of the world and became the foundation of human civilization.
1. Introduction
Before agriculture, humans lived in small groups, depending on wild animals and forest produce. With climatic changes after
