What Is a DaaS "Line"? A Unit That Makes Development Capacity and Speed Visible

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.

3-second summary

  • 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

Most Delivery Bottlenecks Start When Capacity Is Invisible

Typical situations:

  • Every scope change triggers a new estimate, slowing decisions
  • Ownership of "who does what and when" becomes unclear, and tasks pile up
  • Maintenance and new development compete for the same slot, so improvement work stalls

DaaS secures capacity first, reducing common stop causes such as estimate waits, queue waits, and team instability.

1 Line = The Core Unit for "Never Stop Development"

1 line is one team lane in DaaS.

You secure consistent monthly capacity and execute development and improvements based on priority.

What happens with 1 line

  • 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

Example outputs visible in bi-weekly meetings

  • 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.

2 Lines = Two Themes Progress in Parallel, So You Get 2x Speed

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.

Typical 2-line pattern

  • (A) New feature development (offense)
  • (B) Operational improvement and maintenance (defense)

When 2 lines fit best

  • Multiple departments send requests at the same time
  • A system replacement needs migration and new features to run side by side
  • You need to keep up with external changes (regulation updates, partner requirement changes) while continuing development
  • You want to increase release frequency (weekly decisions -> weekly progress)

Difference Between 1 Line and 2 Lines

1 line

  • Backlog -> (priority) -> development -> release -> improvement (single stream)

2 lines

  • Backlog -> A line (new features) -> release
  • Backlog -> B line (maintenance/improvements) -> release

Two streams run at the same time

Bottleneck difference

  • 1 line: queueing is more likely
  • 2 lines: queueing drops, and decision speed also improves

How to Choose a Plan

Light

JPY 298,000/month | 1 line, Web only

You do not want maintenance and minor improvements on an existing Web tool to stop

  • You want to accumulate small improvements steadily
Recommended

Standard

JPY 598,000/month | 1 line, Web + app

New product to growth phase

  • You want to progress Web + app at the same time with Flutter
  • You expect frequent spec changes and want to deliver value quickly

Business

From JPY 980,000/month | 2 lines, Web + app

You want to run new feature development and operational improvement in parallel

  • You need high-speed execution across multiple themes, departments, or short-term replacement projects

Which one fits you?

Maintenance and improvements are stalled

Go with Light / Standard

You want to move new features and improvements at the same time

Common Misunderstanding: "A Line" Is Not a Fixed Deliverable Contract

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:

  • You can start even before all specs are finalized
  • Mid-project direction changes are easier without stopping
  • Because improvements continue, outcomes keep growing

Frequently Asked Questions

How much can we deliver with 1 line?

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.

Is 2 lines simply double the number of people?

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.

Can we switch from 1 line to 2 lines mid-project?

Yes. One strength of DaaS is that it can be adjusted as conditions change (operational rules are aligned at project start).

Why is meeting frequency different by plan?

To match delivery speed with decision cadence. Business is designed for weekly decisions and weekly forward movement.
