Scenario - Waterfall: Building a bridge requires extensive planning upfront—changes during construction are very expensive. All requirements must be perfect before starting.
Scenario - Agile: Building a mobile app with uncertain market needs. Start with core features (1-week sprint), get user feedback, adjust in next sprint. Flexibility helps discover what users actually want.
Planning Tools & Techniques
Gantt Charts
What it is:
Bar chart showing timeline
Horizontal axis = time
Vertical axis = tasks
Shows:
Task duration (bar length)
Start and end dates
Dependencies (which tasks must complete first)
Overlapping tasks (parallel work)
Milestones (key dates)
Benefits:
Visual clarity
Easy progress tracking
Identify delays early
Critical Path Method (CPM)
What it is:
Identifies longest sequence of tasks
Determines minimum project duration
Highlights critical activities
Key concepts:
Slack time: How much delay allowed
Float: Flexibility in timing
Critical tasks: No slack = delay project
Benefits:
Focus on important tasks
Prevent delays
Resource allocation
Planning Components
Milestones: Key checkpoints; mark completion of phases
Dependencies: Tasks that must be completed before others
Resource Allocation: Assign people and equipment to tasks
Risk Assessment: Identify potential issues and mitigation
Contingency Planning: Plans for when things go wrong
Quality Standards: Criteria for acceptable output
Communication
Communication Methods & Tools
Synchronous (Real-time)
What:
Communication happens immediately
Both parties present/available
Instant feedback
Examples:
Face-to-face meetings
Phone calls
Video conferencing (Zoom, Teams)
Instant messaging (Slack, WhatsApp)
When to use:
Complex discussions
Urgent decisions
Problem solving
Building relationships
Asynchronous (Delayed)
What:
Communication happens over time
Parties respond when available
Creates written record
Examples:
Email
Project management tools (Asana)
Shared documents
Forum posts
Status reports
When to use:
Documentation needed
Non-urgent
Distributed teams
Time zone differences
Communication Barriers & Solutions
Key Barriers
Language: Different languages, technical jargon, unclear terminology
Technical: Poor audio/video, connectivity issues
Time zones: Different working hours globally
Misunderstanding: Ambiguous messages, assumptions
Noise: Background noise, interruptions
Cultural: Different communication styles
Overload: Too many messages to prioritize
Solutions
Clear language: Use simple terms, avoid jargon
Feedback: Confirm understanding, ask questions
Scheduling: Plan meetings across time zones
Documentation: Written summaries of decisions
Multiple channels: Email for important, chat for quick
Active listening: Pay attention, don't interrupt
Frequent updates: Reduces misunderstandings
Communication plan: Define how team communicates
Documentation
Types of Documentation
Requirements Documentation: What the project must deliver; specifications
Design Documentation: How the system will be built; technical details
User Guides: Instructions for end users; how to use the system
Test Plans: What testing will be done; test cases and expected results
