Always mark the first version as draft or WIP so that people can give feedback.Adding too many details will make it cumbersome to read. Only have high-level phases in the timeline.If you are looking for multiple projects, then consider - PPT Timeline Multiple.This will help in identifying any cross-project dependencies like resources, environments, etc. Understand what other projects are running at the same time.It is also beneficial to get a feel from the project sponsor or delivery by showing your timeline. It is important to understand the view the management has about the project.

When sending out the details, it is a good practice to run it past a senior manager.It is good to get feedback by showing it to senior managers or project teams to understand glaring issues. Verify the timeline before it is sent out to everyone.Depending on the size of the project, a 10% to 20% buffer should be applied. Always have some contingency in the plan so that you can cover up if something goes wrong.Clearly, highlight any assumptions you have made so that everyone will know how you arrived at a given timeline.Always ensure the effort for tasks is estimated by the actual people doing the tasks.For example, if you have 2 resources and 20 days, you should be completing something in 2 weeks, or your project should run for 10 weeks. Do simple validations - check if several resources are planned work makes sense.So, cover all the countries/states involved. In some cases, the team could be in different geographical locations. Consider public holidays for the project team.Always take into account the resource availability - full-time, part-time, etc.The plan should be communicated in several different methods (E-mails, meetings, large printouts, etc.). After the approval is received, rolling out the plan to everyone is an important step. Stakeholders / Client Approval: Once the three steps above are completed, receiving approval of the plan is the final step.

Their input is a precious, precious feasible plan which is acceptable by all parties.

Brainstorming: Once the first two steps are completed and an initial draft is ready, it should be presented to the team (team members, stakeholders, clients, vendors).

Their predecessors should be clearly marked to plainly see how postponing a certain task will affect the contractual obligations.

Contractual obligations: To ensure that all of the obligations are met, they need to be inserted into their respective groups' timeline.

Each section of the WBS (Engineering, Testing, Interface, etc.) needs to become a group of tasks in the timeline.

WBS: Since 100% of the required work is captured in the WBS, this is a good place to start when outlining a timeline.

To capture a timeline, the following steps should be followed –
