Phases of Waterfall and Agile SDLCs
Waterfall SDLC
Requirements: understanding what is to be designed, functions, and purposes
System design: Preparing system design after studying requirements specifications.
Implementation: writing of the sources as per the requirements
Testing: Testing team checks the code for any potential problems.
Deployment: the project is released into the markets.
Maintenance: this happens after installation. Modifications are made on the system if need be.
Agile SDLC
Concept: project scope determined by the owner.
Inception: the project team is created who also create a mock-up of the user interface and architecture.
Iteration: constructions occur here, and the bare functionality of the product
is built.
Release: Quality assurances team performance test on the product, which is
then released
Maintenance: software is now fully deployed and made avoidable to end-users.
Retirement: replacement of the project if it becomes obsolete.

Waterfall and agile Documentation Differences
Waterfall documentation adopts a sequential methodology where tasks are handled in a liners process.
The tasks are handle in a simple process, one after the other till the end.
Agile documentation adopts an iterative methodology that incorporates a collaborative and cyclic process.
It provides room for the process to move through a series of cycles throughout its lifetime.
Each method can be used depending on the preferences and nature of the project
some projects are more iterative while others are sequential.

Stakeholder’s expectations
The SDLC method to adopt varies depending on the stakeholder's expectations.
The project team:
Expects to have all the time, support, and tools needed to complete the project
Management and executive;
Expects the project to be completed successfully
Expects the project to save on company finances
Clients:
Expects all the requirements o be executed and followed.
The trick to making sure the project runs smoothly is managing all stakeholders' expectations by putting them in balance.
