Here's a list of the pros and cons for each method to help you decide.
WATERFALL
Water fall requires detailed planning at the beginning of a project. All the steps are laid out, dependencies mapped, and you move to the next stage only after completing the previous one.
Pros.
- Best for projects that deal with physical objects - from a construction project to a hardware installation project.
- Best for projects with defined tasks and phases that must be completed in a specific sequence (e.g. build the first floor of a building before the second floor).
- Project plans are repeatable for identical or similar projects in the future.
Cons.
- Requires substantial scope and schedule planning before work begins.
- Scope changes can be slow and require formal change control processes.
- Less effective for software, design and other non-physical or service-based projects.
AGILE
This is a fast and flexible approach to project management based on principles of collaboration, adaptability and continuous improvement. Unlike the orderly stages of a waterfall approach, agile project management is typically set up in quick, iterative project release cycles.
Pros.
- Best for projects that deal with services-oriented and non-physical deliverables like code, copywriting and design projects.
- Allows for quick course correction based on stakeholder feedback.
- Empowers project teams to work creatively and efficiently.
- Includes engagement and collaboration from all team members.
Cons.
- Not suited for projects with strictly defined requirements and scope.
- Uncertainty around scope and schedules can make stakeholders and executives nervous (at first).
- Requires vigilant backlog and documentation maintenance, and tech debt management.
