1. Project Management: Past and Present
🧭 Overview
🧠 One-sentence thesis
Project management skills—planning, communication, resource management, and delivering within cost, schedule, scope, and quality constraints—are essential across diverse careers and have evolved from ancient construction projects to modern methodologies like Gantt charts, PERT, and CPM.
📌 Key points (3–5)
- Core pillars of project management: delivering a product or service within schedule, cost, scope, and quality requirements.
- Universal applicability: project management skills (planning, communication, risk management, budgeting) are used in careers ranging from business owners and educators to engineers, health care professionals, and software developers.
- Historical evolution: project management concepts enabled ancient megaprojects (pyramids, Great Wall) and formalized in the 20th century with tools like Gantt charts (1910s), PERT, and CPM (1950s).
- Common confusion: project management is not just for construction or IT—it applies to any temporary undertaking with a goal, including teaching a class, managing a restaurant, or conducting medical research.
- Modern expansion: today's project management incorporates sustainability, social responsibility, and environmental considerations alongside traditional cost/schedule/scope constraints.
🌍 Project Management Skills Across Careers
🏢 Business Owners
Business owners need planning, organizing, scoping, analyzing, communicating, budgeting, staffing, equipping, implementing, and delivering skills.
- Why it matters: successful businesses deliver products/services that meet customer needs in quality, cost, and timeliness—the same pillars as project management.
- What they do: understand finances, operations, expenses; may focus on accounting, sales, training, public relations, or logistics.
- Example: A business owner managing a storefront or travel agency applies project management principles to coordinate operations and meet customer expectations.
🍽️ Restaurant Owner/Manager
- Planning and coordination: synchronize kitchen, dining room, banquet operations, vendors, and staff schedules to satisfy customers.
- Risk management: ensure food safety, monitor kitchen delays, comply with legal standards (especially alcohol service).
- Financial tracking: analyze recipes for cost (food, labor, overhead), assign menu prices, order supplies, and manage catering events.
- Scheduling: time staff shifts, food deliveries, equipment maintenance, and cleaning during slow periods.
- Don't confuse: restaurant management is not just "cooking and serving"—it requires the same project planning, resource allocation, and quality control as any project.
🏗️ Construction Managers
- Core responsibilities: plan, direct, coordinate, and budget residential, commercial, and industrial construction projects.
- Scheduling and communication: coordinate design, construction teams, specialized trades (carpentry, plumbing, electrical), and government permit processes.
- Tools: use software like Microsoft Project, Procure, or Basecamp; rely on spreadsheets for tracking.
- Procurement and labor: acquire materials (lumber, bills of material), coordinate labor, oversee performance to ensure on-time completion.
- Modern values: incorporate sustainability, LEED certification, green energy, and energy efficiency into projects.
- Example: A construction manager divides a building project into logical steps, estimates time and budget, and ensures compliance with safety codes and quality specifications.
🎨 Graphic Artists
- Initiation and planning: determine client needs, the message the design should convey, and its appeal to the target audience.
- Communication: meet with clients, creative staff, art directors; brainstorm and research to ensure high quality and manage risks.
- Execution: use color, type, illustration, photography, animation, and layout techniques to create print and electronic media (magazines, brochures, websites, apps).
- Resource management: supervise assistants, schedule tasks, monitor costs, use computer and communications equipment efficiently.
- Don't confuse: graphic design is not just "making things look nice"—it involves cognitive, cultural, physical, and social factors similar to stakeholder analysis in project management.
👩🏫 Educators (Teachers)
- Planning and evaluation: plan and assign lessons, implement plans, monitor each student's progress (like a project manager monitors deliverables).
- Communication and facilitation: act as facilitators or coaches, manage students, parents, and administrators.

📜 Historical Evolution of Project Management
🏛️ Ancient Projects
- Early examples: hunting parties of prehistoric ancestors, pyramids, Great Wall of China, Stonehenge.
- Key insight: project management concepts have existed since the beginning of organized human activity, enabling leaders to plan massive projects and manage funding, materials, and labor within a time frame.
🚂 Late 19th Century: Large-Scale Government Projects
- Catalyst: large-scale U.S. government projects like the transcontinental railroad (1860s construction).
- Challenge: organizing manual labor of thousands of workers and processing unprecedented quantities of raw material.
- Outcome: business leaders developed decisions that became the basis for project management methodology.
📊 1910s: Gantt Charts
A Gantt chart is a bar chart that illustrates a project schedule, representing the phases and activities of a project so they can be understood by a wide audience.
- Developer: Henry Gantt studied the order of operations in work and developed the Gantt chart in the 1910s.
- Impact: considered revolutionary at the time; employed on major U.S. infrastructure projects (Hoover Dam, interstate highway system).
- Legacy: still accepted today as important tools in project management.
⚛️ Mid-20th Century: Manhattan Project
- Context: code name for the Allied effort to develop the first nuclear weapons during World War II.
- Scale: over 30 project sites in the U.S. and Canada, 130,000 people, nearly US$2 billion, multiple production and research sites operated in secret.
- Significance: complexity was only possible because of project management methods; succeeded in developing and detonating three nuclear weapons in 1945.
- Management approach: ad hoc basis using mostly Gantt charts and informal techniques and tools.
📐 1950s: Modern Project Management Era
🔗 PERT (Program Evaluation and Review Technique)
PERT is a method for analyzing the tasks involved in completing a project, especially the time needed to complete each task, the dependencies among tasks, and the minimum time needed to complete the total project.
- Developer: Booz-Allen and Hamilton for the U.S. Navy's Polaris missile submarine program.
- Purpose: mathematical project-scheduling model.
🛤️ CPM (Critical Path Method)
The critical path method determines the float (schedule flexibility) for each activity by calculating the earliest start date, earliest finish date, latest start date, and latest finish date for each activity.
- Developer: joint venture by DuPont Corporation and Remington Rand Corporation for managing plant maintenance projects.
- Key concept: the critical path is generally the longest full path on the project; any activity with zero float time is a critical path task.
- Benefit: helps determine how long a complex project will take and which activities are critical (must be done on time or the whole project will take longer).
- Spread: these mathematical techniques quickly spread into many private enterprises.
🏢 1960s: Organizing Work Around Projects
- Shift: industrial and business organizations began to understand the benefits of organizing work around projects.
- Recognition: critical need to communicate and integrate work across multiple departments and professions.
- Outcome: project management in its present form began to take root.
🌱 Modern Project Management Values
🌍 Sustainability and Social Responsibility
- Expanded vision: financial, environmental, and social areas are now part of project management.
- PMI Code of Ethics: project managers should include in their decisions the best interests of society, the safety of the public, and enhancement of the environment.
- Triple bottom line: in addition to cost, scope, and schedule, a project manager should ensure the project is:
- Socially responsible
- Environmentally sound
- Economically viable
- Example: Construction managers incorporate sustainability, reuse, LEED-certified building, green energy, and energy efficiencies into today's projects with an eye to the future.
