Technology and architecture consulting

Yes. Naming a product on this site does not mean a partnership with its vendor, and our recommendation follows your requirements, skills and budget, including keeping what you have when that is the better answer. If we would like to deliver the work ourselves, we say so openly, and the plan is written so any competent team can deliver it.

Before a decision that is expensive to reverse: choosing or replacing an ERP or core platform, designing how many banks and partners will connect, moving to the cloud, or recovering a project that is late. It is also useful before raising investment or buying a company, when you need an outside view of a technology estate. For small, reversible choices, a short call is usually enough.

Written documents, not just a presentation: an assessment of the current state, a target architecture, the options compared with a recommendation, decision records, and a phased roadmap with an estimate and its assumptions. We walk your team through each one and update them after your review.

Usually as a fixed scope with a fixed fee, agreed after a short scoping conversation, or as a number of consultant days for open-ended advisory work. The price depends on the size of the estate to review, the number of options to compare and the depth of analysis the decision needs. You see the price and the timeline before we start.

It depends on the size of the question and how quickly we can reach the people, documents and systems involved. A focused review of one system or decision is short; an assessment of a whole technology estate takes longer. We agree the scope and the date of the final readout before we start.

Usually read-only access to documentation, code repositories, architecture diagrams and monitoring, plus time with the people who run the systems. We do not need production data for most reviews. Access is granted to named people, under a non-disclosure agreement, and removed when the engagement ends.

Yes, if you want us to. The same architects can stay on to guide delivery, and we can provide a dedicated team, augment your own engineers or deliver a defined project. There is no obligation: the roadmap is yours to deliver with any supplier or your own team.

Yes. We will sign a mutual non-disclosure agreement before you share anything confidential, on your template or ours. Everyone who works on your project is bound by confidentiality obligations, whether they are XSIS employees or members of an outsourced team.
