Overview:

There are plenty of elements of project objectives that you could think about.

These vary from producing plans to communication. An excellent leader ought to realise these.

Allow plans to be put together:

In the absence of excellent project management objectives it is harder to make a precise checklist of the tasks needed, that is, the work breakdown structure.
When the project goal is dissected into controllable pieces, as objectives, the work breakdown structure begins to be more reasonable. From this the activity timings are more precise and the project schedule has strengthened validity.

Arrange and prioritise work:

Specifying excellent objectives permits individuals to plan daily jobs with more confidence.

This indicates improved time management and ought to lead to higher effectiveness.

Motivation of the personnel:

Excellent leaders will only profit more from making certain that objectives are well founded. This will result in sharper processes and a much better possibility of project management success.
This in turn will aid project management team motivation, which again can only strengthen the long-term possibility of project success.

Conveying the project management target:

A key feature of leadership is to broadcast the target of the project and to promote it to the project management team and stakeholders.

It's impossible to do this if objectives are unclear. Once again, transparency will boost communication and increase motivation.

Allows acknowledgment of success:

Transparent objectives permit the creation of accurate standards for their fulfillment and, as a result, achievements at particular phases of a project.
This makes things easier for the Project Manager to praise people and teams for their results. Objectives invite effective practice in reviews, and other features, for instance delegation. The latter is simpler when the objective is explicit.

PRINCE2:

PRINCE2 recognises products as the mainstay of its product-based method.

These are anything that may be determined as an output. This would typically consist of work packages which will have requirements for their completion. Likewise, project management objectives will be deemed products. They also create an outcome and have a need for achievement criteria.

The focus is on output and not on the particular jobs themselves.
Defining products or objectives before the project commences is compulsory. In turn, objectives will define the project management scope. See the sections for PRINCE2 2009 'Principles - Focus on products' and 'Plans - The PRINCE2 approach - Define and analyze the products'.

Using this method PRINCE2 projects generate a product breakdown structure; contrast this to the work breakdown structure (wbs). For PRINCE2 2009 see the section 'Plans - The PRINCE2 approach - Prerequisites for planning-- design the plan - Create the product breakdown structure'.
