All knowledge areas (as per PMI) in a LSP are influenced by the level model. The topics that are crucial in all LSPs are described in the next chapters:
One of the most important - and often overlooked - part in a LSP is the set-up of an adequate governance. That incorporates all internal and external influences of different levels. It is recommended to create a clear structure which divides the several views in a project to the three level. This structure enables all stakeholder to receive and to give the contribution that is required by them in a clear way.
Drafting a valid basis for all work that has to be done is often called "The Art of Planning" because it is like creating a piece of art. There are many books, articles and blogs that deal with this topic. The planning in a LSP is certainly a challenge and must be practiced very carefully. Most of the planning items are analyzed on the three levels according the LPLM.
An adapted risk management is an important part of all LSPs. Treatening this topic properly may reduce the failure of a project significantly. For this section applies the same assumption as for the planning: All activities are discussed in relation to the three level as described before.
All successful LSPs have certainly something in common: They always implement innovative improvement measures. It does not mean that the project has to be changed continuously but it will undergo many steps of improvement during its life-cycle. This topic is not directly related to the LPLM but it influences the work in and the relation between those levels.
Other topics of project management influence the success of a LSP by using the LPLM less than the above mentioned. Nevertheless, there are several areas that are described in the next chapters because they are somehow significant to understand and apply the level model.
