Meet with other staff that are users of IT and get their perception of the services – don’t promise anything other than to look / investigate at this stage.

Are there different levels of filtering for execs, managers and general staff, or special teams like Comms and Marketing?

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.

how will you record your progress, success, issues and documentation. Is there a wiki or sharepoint site? Do you need a document repository making? Is there documentation in place, and how good is it? Is there a standard to aim for? Does the company recognise the importance of documentation?

is there any, in what departments, and to what level. How many admin accounts are there, and who has access. Is IT seen as a thing that slows you down and stops you getting stuff done, and thus something that needs to be bypassed? Do people doing / using shadow IT have legitimate issues, or political power that prevents dealing with them directly.

Alongside the information to gather, there’s a list of things I will be trying to get / ensure I have available to ensure I can work well:

  • Dalek for server room / comms rooms, Pegboard with hooks, selection of patch cables in colour / size to match scheme, coloured power cables in various sizes, louvre panel and clip bins, stacking crates or decent shelves / storage for spares and IT equipment – must be somewhere secure for high value kit

  • Week 1 – speak with managers, peers, staff, and other departments. Do intro to business, start gathering data and try to get a brief summary. Establish the Tier 1 triage – what is on fire, what is smouldering, what are rocks that might have creatures underneath them, but can be left alone for now.
  • Week 2 – try to visit sites, get floorplans with some information on, start documenting systems, getting network mapped in Visio, establish better idea of critical fixes and state of play. By the end of week 2, try to have at least one minor win – something you have achieved, fixed or replaced with something that now works properly to show some kind of progress.
