get to know the following key people, and make friends – the receptionist who will screen your calls, or look after your visitors. The person who organises stationary, admin supplies or books couriers and can make deliveries happen as if by magic. The M&E engineer who can sort out power, lighting and aircon issues for you, and arrange access through locked doors all over site. The HR person who sorts out timesheets, flexitime, overtime and cover. The payroll person to looks after expenses, petrol claims, invoicing and payroll.
You need to be able to describe your work and projects in ways that at least justifies existence and at best terrifies Management so they won't want to cut your budget. Also be able to express the importance of every project in terms of either generating money or risk mitigation to avoid losing money. Business is all about revenue and many managers see IT as an unpleasant expense rather than as an important tool which enables their employees to make money. Asset Management either means ugly stickers that the helpdesk uses instead of actually fixing the computer thingy, or it means a streamlined system of inventory management which enables faster issue resolution, ensuring your colleague is returned to a productive state as soon as possible.
