Create comprehensive WBS, timelines, and resource plans in 30 minutes instead of 4-6 hours
By the end of this module, you will be able to:
You've just been assigned a new project. Your executive sponsor wants a detailed plan by end of week. Here's what you're facing:
Total: 10.5 hours of intense planning workโand you haven't even started the project yet.
With ChatGPT, you can create the same comprehensive plan in 30 minutes. Here's how.
A Work Breakdown Structure (WBS) is the foundation of project planning. It breaks your project into manageable phases, deliverables, and tasks. Here's how to create one with ChatGPT.
Clearly describe what the project will deliver and any constraints
Use AI to create the high-level structure and major phases
Break each phase into detailed, actionable tasks
Review with your team and adjust based on their expertise
Let's walk through a real example. You're managing an e-commerce website redesign project.
The more context you give ChatGPT, the better your WBS will be. Include:
I'm managing an e-commerce website redesign project. Help me create a comprehensive Work Breakdown Structure (WBS).
PROJECT DETAILS:
- Goal: Redesign our B2C e-commerce site to increase conversion rate by 30%
- Timeline: 4-month project with November 15 launch deadline
- Team: 2 UX designers, 3 developers, 1 QA engineer, 1 content writer
- Key Features: New homepage, product pages, checkout flow, mobile optimization, payment gateway integration
REQUIREMENTS:
- Break down into major phases (Discovery, Design, Development, Testing, Launch)
- Include all deliverables and tasks
- Consider dependencies between tasks
- Format as a hierarchical structure (Level 1: Phases, Level 2: Deliverables, Level 3: Tasks)
- Include estimated effort (hours or days) for each task
ChatGPT will generate a comprehensive WBS. Here's what you'll typically get:
WORK BREAKDOWN STRUCTURE: E-Commerce Website Redesign
1.0 DISCOVERY & PLANNING (2 weeks)
1.1 Stakeholder Alignment
1.1.1 Conduct kickoff meeting with sponsors (4 hours)
1.1.2 Document business objectives and KPIs (8 hours)
1.1.3 Define success metrics (4 hours)
1.2 User Research
1.2.1 Analyze current site analytics (16 hours)
1.2.2 Conduct user interviews (20 hours)
1.2.3 Create user personas (12 hours)
1.2.4 Map current user journey (8 hours)
1.3 Competitive Analysis
1.3.1 Research competitor websites (12 hours)

2.1.4 Revise based on feedback (12 hours)
2.2 Visual Design
2.2.1 Develop design system (colors, typography, components) (24 hours)
2.2.2 Create high-fidelity mockups (48 hours)
2.2.3 Design mobile-responsive versions (24 hours)
2.2.4 Stakeholder review and approval (8 hours)
[... continues with Development, Testing, and Launch phases ...]
Need more detail on a specific phase? Just ask:
Expand section 3.0 Development Phase in more detail. Break down the checkout flow development into specific technical tasks, including:
- Frontend development tasks
- Backend API development
- Payment gateway integration steps
- Database schema changes
Include dependencies and specific technologies (React, Node.js, Stripe)
Once you're happy with the WBS, get it in a format you can use:
Export this WBS in CSV format with columns: Task ID, Task Name, Phase, Estimated Hours, Dependencies, Assigned Team Member Role
Make it ready to import into Microsoft Project or Jira.
A WBS tells you what needs to be done. A timeline tells you when and in what order.
Task B can't start until Task A finishes. Most common.
Example: Can't start Development until Design is approved
Task B can start when Task A starts (parallel work).
Example: Content writing starts when Design starts
Task B must finish when Task A finishes.
Example: Testing finishes when final bug fixes finish
Task B can't finish until Task A starts. Rarely used.
Example: Old system runs until new system starts
Now let's turn your WBS into a realistic project timeline:
Based on the WBS we created, generate a project timeline for the e-commerce redesign project.
CONSTRAINTS:
- Project must complete by November 15 (16 weeks from today)
- Team works 40 hours/week
- Developers can only work 1 feature at a time
- Design must be approved before development starts
- Testing requires completed development
PLEASE PROVIDE:
1. Start and end dates for each major phase
2. Critical path (tasks that directly impact the end date)
3. Task dependencies (which tasks must finish before others start)
4. Identification of any resource conflicts or bottlenecks
5. Buffer time for unexpected delays (10% contingency)
Format as a Gantt-chart-ready table with: Task Name, Duration, Start Date, End Date, Dependencies, Assigned Role
AI-generated timelines are starting points, not final schedules. Always:
You know what needs to be done and when. Now you need to figure out who does whatโand whether you have enough people.
Create a resource allocation plan for the e-commerce redesign project.
TEAM COMPOSITION:
- 2 UX/UI Designers (Sarah - Senior, Mike - Mid-level)
- 3 Frontend Developers (React specialists)
- 2 Backend Developers (Node.js/Express)
- 1 QA Engineer
- 1 Content Writer
- 1 Project Manager (me)
REQUIREMENTS:
1. Assign roles to each task in the WBS
2. Calculate total hours per person per week
3. Identify resource bottlenecks (anyone over 40 hours/week)
4. Suggest where we might need contractors or additional help
5. Highlight skill gaps (tasks we don't have expertise for)
6. Recommend task sequencing to balance workload
Present as a week-by-week resource allocation table showing:
- Person name and role
- Tasks assigned that week
- Total hours allocated
- % capacity utilization
- Any conflicts or overallocations
ChatGPT will identify resource issues like:
๐จ Overallocation: Sarah (Senior Designer) is assigned 65 hours in Week 3. Need to redistribute work or extend timeline.
โ ๏ธ Skill Gap: Payment gateway integration requires Stripe API expertise. None of your developers have this experienceโconsider bringing in a contractor.
๐ก Opportunity: Mike (Mid-level Designer) is only 50% utilized in Weeks 5-6. He could help with design documentation or start on marketing materials early.
Use ChatGPT's insights to:
Once you've mastered basic WBS and timeline creation, try these advanced prompts:
Identify which tasks directly impact your deadline
Build contingency plans for high-risk tasks
Find opportunities to run tasks in parallel
Plan for best-case, worst-case, and most-likely scenarios
Scenario: You're launching a new mobile fitness tracking app for iOS and Android.
Requirements:
Task: Create a complete WBS, timeline with dependencies, and resource allocation plan using ChatGPT.
I need to plan a mobile fitness tracking app launch project. Help me create:
1. Comprehensive Work Breakdown Structure (WBS)
2. Project timeline with task dependencies
3. Resource allocation plan
PROJECT DETAILS:
- Timeline: 3 months from today (launch date: [INSERT DATE])
- Platform: iOS and Android native apps
- Team: 1 iOS developer, 1 Android developer, 1 backend developer (Node.js), 1 UX/UI designer, 1 QA tester

* User registration/login (email + social auth)
* Workout logging (custom workouts, sets, reps, weight)
* Progress tracking (charts, stats, personal records)
* Social features (share workouts, follow friends)
* Integration with Apple Health and Google Fit
- Backend: REST API + PostgreSQL database
SPECIFIC REQUIREMENTS:
- Break into phases: Planning, Design, Development (Backend + Mobile), Testing, Launch

- Include app store submission process (1 week review time)
- Add 15% buffer for unexpected delays
OUTPUT FORMAT:
- WBS with 3 levels of detail
- Timeline as Gantt-ready table (Task, Duration, Start, End, Dependencies)
- Resource allocation showing hours/week per person
- Critical path analysis
- Risk areas to watch
