Introduction

Time to Market (T2M) measures how quickly an organization can deliver new value. It is not about working faster — it is about eliminating waste in the delivery pipeline so that value reaches users sooner.

A team that ships every two weeks has a T2M advantage over a team that ships quarterly — not because they work harder, but because they have fewer handoffs, shorter feedback loops, and less bureaucracy between idea and delivery.

Lead Time vs. Cycle Time

In the T2M context:

  • Lead Time: Total time from when an idea is first conceived to when it reaches users. This includes waiting time, approval time, development time, testing time, and deployment time.
  • Cycle Time: The subset of lead time when active work is happening.

The gap between lead time and cycle time is waste. If your lead time is 90 days but cycle time is 10 days, then 80 days are spent waiting, in queues, or in approvals. Reducing T2M means attacking those 80 days, not making developers code faster.

Example T2M Metrics

  • Release Frequency: How often you deploy to production. Weekly? Monthly? Annually?
  • Release Stabilization Time: How long after a release before it is considered stable? Long stabilization = low confidence in quality.
  • Lead Time for Changes: Time from code commit to production deployment. High-performing teams: less than 1 day. Low performers: more than 6 months (DORA metrics).
  • Build and Integration Frequency: How often code is integrated and tested. CI/CD pipelines reduce this to minutes.

Value Stream Mapping

Value Stream Mapping (VSM) is a technique for visualizing the entire delivery process from idea to production. For each step, record:

  • Process time (active work)
  • Wait time (queue, approval, handoff)
  • Percentage complete and accurate (%C&A)

The result reveals where value is created and where time is wasted. In most organizations, less than 20% of lead time is active work. The rest is waiting.

Strategies for Reducing T2M

  1. Automate the pipeline: CI/CD eliminates manual build, test, and deploy steps.
  2. Reduce batch sizes: Smaller releases go through the pipeline faster.
  3. Eliminate handoffs: Cross-functional teams own the entire pipeline from code to production.
  4. Reduce approval gates: Trust the team and the automated tests. Manual approval is a queue.

Key Takeaways

  • T2M measures speed of value delivery, not speed of work.
  • The gap between lead time and cycle time is waste.
  • Value Stream Mapping reveals where time is wasted.
  • Reduce T2M by automating, reducing batch size, eliminating handoffs, and reducing approval gates.

概述

上市時間(T2M)量測組織能多快交付新價值。不是要工作更快,是要消除交付管道中的浪費。

前置時間 vs. 週期時間

前置時間:從構想到使用者收到的總時間。週期時間:實際工作進行的部分。差距就是浪費。如果前置時間 90 天但週期時間 10 天,那 80 天都在等待。

價值流圖

視覺化從構想到產品的整個交付流程。在大多數組織中,不到 20% 的前置時間是主動工作,其餘都是等待。

降低 T2M 的策略

  1. 自動化管道:CI/CD 消除手動步驟。
  2. 縮小批次大小:較小的發佈通過管道更快。
  3. 消除交接:跨職能團隊擁有從程式碼到產品的整個管道。
  4. 減少審批關卡:信任團隊和自動化測試。

重點整理

  • T2M 量測價值交付的速度,而非工作的速度。
  • 前置時間和週期時間的差距是浪費。
  • 價值流圖揭示時間浪費的位置。

概要

市場投入時間(T2M)は、組織が新しい価値をどれだけ速く提供できるかを測定する。速く働くことではなく、デリバリーパイプラインの無駄を排除することだ。

リードタイム vs. サイクルタイム

リードタイム:アイデアからユーザーに届くまでの総時間。サイクルタイム:実際に作業が行われている部分。ギャップは無駄だ。

バリューストリームマッピング

アイデアから本番までのデリバリープロセス全体を可視化する。ほとんどの組織で、リードタイムの20%未満が能動的な作業。残りは待ち時間だ。

T2M削減の戦略

  1. パイプラインの自動化
  2. バッチサイズの縮小
  3. ハンドオフの排除
  4. 承認ゲートの削減

重要ポイント

  • T2Mは価値提供の速度を測定し、作業速度ではない。
  • リードタイムとサイクルタイムのギャップが無駄。
