In DaaS, a "line" is a practical lane of capacity that keeps development moving forward.
Instead of fixed-scope delivery contracts, you secure monthly capacity and keep stacking outcomes over time.
1 line: one stable team lane that keeps delivery from stopping
2 lines: two themes in parallel = 2x speed (for example, new features plus improvements)
If unsure: Standard (1 line) for new-to-growth, Business (2 lines) for simultaneous multi-theme work
Typical situations:
DaaS secures capacity first, reducing common stop causes such as estimate waits, queue waits, and team instability.
1 line is one team lane in DaaS.
You secure consistent monthly capacity and execute development and improvements based on priority.
Requirements -> design -> implementation -> test -> release runs continuously
Even when specs change, work is adjusted and keeps moving without stopping
With Web + app (Flutter), you can expand scope in parallel under the same flow
Working screens (demo)
Change summary (what became possible)
Priority proposal for the next two weeks
When needed: spec notes and simple diagrams (operation flow / screen transitions)
Important: a line is not a guarantee of a fixed number of screens. It is a capacity lane to maximize outcomes.
With 2 lines, the benefit is not only more people. The nature of bottlenecks changes.
With 1 line, offensive and defensive work often compete for the same lane. With 2 lines, both keep moving, which adds management-level confidence.
Two streams run at the same time
JPY 298,000/month | 1 line, Web only
You do not want maintenance and minor improvements on an existing Web tool to stop
JPY 598,000/month | 1 line, Web + app
New product to growth phase
From JPY 980,000/month | 2 lines, Web + app
You want to run new feature development and operational improvement in parallel
Maintenance and improvements are stalled
Go with Light / Standard
You want to move new features and improvements at the same time
Go with Business
A line is not a fixed contract saying "we will deliver this exact feature." It is a contract to maximize the value of monthly development capacity based on changing priorities.
That is why:
It depends on scope and complexity. We first define the minimum success condition (MVP), then keep moving with the shortest path while reviewing working outputs in bi-weekly meetings.
The team does expand, but the biggest difference is that two themes advance in parallel without blocking each other. New features and maintenance no longer fight for the same lane, so speed increases.
Yes. One strength of DaaS is that it can be adjusted as conditions change (operational rules are aligned at project start).
To match delivery speed with decision cadence. Business is designed for weekly decisions and weekly forward movement.
