Not a consultancy that recommends and leaves — SIer consulting.
ITSN, Inc.'s consulting is distinguished by the same team owning everything from upstream design to implementation. Current-state analysis, grand design, requirements definition, and basic design are delivered as tangible deliverables — an assessment report and design documents, followed by hands-on support once agreed, and then system construction built exactly to the design. This is support built on the premise that the same people who designed it see it through to completion, not a consultant who is "just there."
Upstream work is a critical investment that determines whether a business initiative succeeds. At the same time, we often hear the anxiety that "all we see is billed hours piling up, with little clarity on what actually remains in hand." We resolve this anxiety structurally, by making the entry point a tangible deliverable and by having the same people who designed it carry it through to implementation.
Fees accrue against hours worked, and the shape of the deliverable is hard to see. You receive recommendations, but implementation goes to a different company, and the design intent doesn't always reach the people building it.
The entry point is a clear deliverable (fixed fee) — an assessment report and design documents. What you'll end up with is clear from the start. And because the same ITSN that drew up the design also carries it through to implementation (our core system-building business), delivery is end-to-end.
Each of the three areas has its own entry-point "assessment & design menu" (deliverable-based). You can also start small — with an assessment in just the area you need.
We map the IT-wide picture from a management perspective. From a current-state inventory to an investment plan, overall system vision, and roadmap, we help management and frontline teams work from the same map.
Entry menu: IT current-state assessment report / Grand design document
We untangle your business operations and translate the "target state" into concrete requirements. We organize siloed processes and fragmented data, and design DX initiatives with clear priorities.
Entry menu: Process visualization & issue assessment report / Requirements & basic design document
We design the architecture of your technical foundation. We draw up a configuration covering network, cloud, and security in an implementable form, backed by ITSN's own infrastructure build track record.
Entry menu: Infrastructure assessment / Architecture design document
By making the entry-point "assessment & design" phase a deliverable-based fixed-fee contract, cost is tied directly to output. Once trust is established, we move into hands-on support, and then implementation. At each phase, we make clear the contract type and the value you receive.
As an independent SIer, ITSN has handled everything from requirements definition through construction and operational maintenance in-house. That's precisely why we can draw up upstream consulting as "a design that can actually be built." We don't let it end as a plan on paper — because the same people who designed it carry it through to implementation, the design intent reaches the field.
Even if committing to a large contract right away feels risky, you can start small with a deliverable-based assessment & design menu. After reviewing the first deliverable (assessment report and design documents), you can decide whether to move on to the next phase.
If you already work with ITSN on implementation or operations, you can hand off upstream design for fully end-to-end delivery. A team that already knows your environment takes on the upstream work, eliminating the disconnect between design and implementation and optimizing the whole.
"We want to figure out where to start" — "We're looking for a partner we can hand the upstream work to" — we welcome inquiries at this stage. With our deliverable-based assessment & design menu, you can take a low-risk first step.
