What is the advantages and disadvantages of traditional project
management and agile project management?
Traditional project management (Waterfall) is linear where all
the phases of process occurs in sequence. Agile project management
is an iterative method for software development projects , It is
based on the delivery the requirements of the project incrementally
and iterative throughout the development life cycle of project.
Advantages of Agile:
- Rapid delivery of project: deploy the product or software
quicker
- less waste of resource: You always work on up to date task
- more profitability for achieving the objective of
projects.
- Up front work will be less.
- You can detect and fix the defect faster.
- beneficial for projects with flexible objective which can
undergo mid scope changes.
- Turn around time is faster.
- you can get immediate feedback.
Disadvantages of Agile:
- Project deadlines and costs are difficult to communicate
- Need more resource for completion of project, sometimes project
may go over budget
- All stakeholders need to take time to involve in the daily
meetings and progress.
- Difficult to measure the progress, because progress happens
across several cycles.
- It demand more time and energy from everyone, because
developers and customers must constantly interact with each
other.
- Project can also become ever lasting, because there is no clear
end.
- In sufficient training
- Lack of predictability.
- Agile will be more challenging for larger projects.
Advantages of traditional project
management:
- This approach often results in accurate budget and timing.
- Gives more confidence about final product earlier in the
development life cycle.
- Project team members need not to be co- located although risk
associated with this is managed.
- Easy to explain to the users.
Disadvantages of traditional project
management:
- There no process defined to go back to the previous stage to
make the changes in requirement, since any phase in the project
development process starts only after the previous phase is
completed.
- Traditional project management is structured SDLC method where
schedule is rigid.
- You can not start developing project until and unless all the
requirements are clear.
- Risk is higher as compared to agile methodology, if any issue
occurs or change in the scope arise in middle of development cycle
it will add high cost and risk in order to make the changes
later.
