Keys to a Successful Project Management Office (PMO)
Introduction
Tailoring the PMO function to the needs of a given business, whether explicit or implied, is crucial. The organisation should be able to deliver their projects and meet desirable outcomes through this process. Successfully delivering projects and meeting goals will determine if your PMO is "fit for purpose."
The degree of support from the PMO will mirror an organisation's complexity - how much they help with achieving goals depends on what changes need to be made in order for them to do so successfully. When considering change management within an organised company, it's important that you take into consideration what has been successful before in helping other teams achieve success- just because something worked once doesn't mean it'll have a positive outcome every time!

Defining a clear vision
A clear vision for the PMO is to establish it as a strategic partner within the business. The best way to do this is by setting up flexible processes, short feedback cycles and learning agility which will help with uncertainty and ambiguity. Keeping people engaged becomes easier when you all share a common purpose in your organization (The result of your function).
Define the purpose of your function and align that with the goals of your organization in order to create a common goal. Consider how you're going to set up an effective reward system, which will encourage desired behaviours.
The PMO should act as a strategic partner within the business by knowing both its present state and strategic objectives, continuously evolving its operating model in line with changing requirements within the organisation.
It is important for project management offices to get the context right concerning organizational interdependence and constraints between projects. Proactively eliminate duplication of project efforts by taking an enterprise view of the business landscape. It's not just reallocating under-utilisation of funds to reinvest in other projects quickly, it is also about avoiding investing in wrong projects from the start through effective stakeholder relationships and communication supported by collaboration and cross-functional teamwork.
The importance lies with encouraging early warning if a project will not meet its intended timing or outcomes, which avoids wasting money even though this may cause uncertainty for resources within that particular project.
Organise your structure and processes
Your PMO should be using technology to the fullest extent to provide timely, accurate and relevant information for key decision-makers. Work smarter, not harder by moving away from various spreadsheet templates and more complex software tools towards a better integration of collaboration features.
Measure time and cost metrics against the quality of delivery or work done on a project as opposed to just working blindly on some standard template for reporting. What does it take? Having the right software is one thing but what's really needed are proactive project managers who can use that information in order anticipate any upcoming failing projects before it's too long since they begin without even realizing there was such an issue at hand in the first place!
If any given path you're trying out isn't showing clear signs of success then your PMO steps up to manage this uncertainty with ambiguity so you don't have things go wrong unexpectedly when determining how best replace resources or alter processes accordingly based on which ever methodology is required whether linear, iterative or hybrid - assigning appropriate resources where necessary for support during implementation.

Upgrade your skills
A good PMO needs the right balance of skills and experience. It should have both seasoned professionals as well as people with the right enthusiasm and attitudes who are able to develop into an effective team that can grow.
The PMO must be up-to-date always, or else it risks losing relevance due to its lack of awareness about latest trends in technology or business models. To maintain this relevance, continual technical training, coaching and development is necessary for capable teams (which consist mainly of experts). Look at new technologies for opportunities to shift functions within your company; don't limit yourself by sticking with what was already working before - there may be better options out there! Don't forget that if you want continuous growth then challenging whether legacy infrastructure makes sense is also important (don’t forget its effect on future generations!).
A successful PMO will not only remain relevant but will also shift seamlessly from one generation to another leaving a great reputation behind through collaboration instead of competition among employees. This type of atmosphere would encourage trust between colleagues.
