How to work towards a common goal when everyone has its own agenda ?

My 5th day at work. Probably won't be my first choice in the companies I would want to work for. It is big and damn big but there are too much rumours out there on how much you time and effort you had to invest in. I felt it could be a good platform for me to take the challenge ....

Today I witnessed something in which not only time and effort I will be putting in. Your mental buffer to take shit of any form must be very adequate, if not, probably you would just disintegrate into the air.

To blend in a new environment takes time, you have to identify and remember key people of each teams which can help you with your agenda. Sometimes, it is a direct help, or could be a collaboration, or could be you need to help them, etc.

Almost every work there will be projects, whether be it technology related or not. So you could be competent in certain areas whether technically or management wise or co-ordinating wise or communication wise or PR wise or abit of everything. So PMI or CITPM comes in place, it basically gives you a guideline on how to successfully plan, execute, control and deliver a project on time and on budget.

I come to realise that it can only be a foundation to work on as other critical factors really surpasses PMI or CITPM. Like ...

Corporate Culture
Corporate Processes and Policies
Local and Regional Restriction
Office Politics
Relationships
Individual Work Load

Someone with substantial weight send an email which I did not get a chance to read but definitely has its blend of sweet and short pricks, ironic sarcasism, etc. This was send to my boss's boss's boss's boss. So boss obviously was agitated and try to "big issue make small, small issue make nothing". It was a string of unfortunate events that lead to this which I felt can be prevented or at least very much mitigated.

A rule that worked everywhere. You might have did 1,000,000,000,000 good things and if you did a mistake ....... Just be prepared. The tolerance level for mistakes in today's working environment is as little as you can imagine.

Sometimes you would overlook certain details, simply there is just a limit that one person can do or handle or co-ordinate at a time or time frame. Therefore, the so called the Project Manager or the "Scape Goat" must be steady pom pi pi, if not ... can only pray. But then, this always is not the case.

Of course, he can also hope that his team steady pom pi pi then maybe he can rely on them. Then usually, this "team" rarely is dedicated and are shared resources so it is back to the "there is just a limit that one person can do or handle or co-ordinate at a time or time frame" rule.

Anyway, part and parcel of work. Basically 2 options, do or don't do. Soon my turn to take on the role of "How to work towards a common goal when everyone has its own agenda". Let's see how it goes ...
