A sample answer to question 1

How do you approach the first weeks of a consulting engagement with a new client to understand their IT environment and needs?

I begin by clarifying the scope, objectives and success measures with the sponsor, then listen widely: interviews with executives, IT staff and business users, plus reviews of documentation, architecture diagrams, service reports, contracts and budgets. I try to understand the business context first, such as strategy, customers, regulatory pressures and recent incidents, so my recommendations fit reality. I use workshops and process walk-throughs, and where possible I examine data, such as ticket trends, network or cloud cost reports, and application inventories. I keep a risk and assumptions log, and I test early hypotheses with the client in short playbacks, so we correct misunderstandings before they become expensive. By the end of the first couple of weeks, I would present a concise baseline and a refined plan. I also take care to build relationships with the people who will implement or live with my advice, because recommendations only succeed if they are owned by the client.

Common mistake to avoid: Starting with solutions; Only talking to senior stakeholders
