SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

締め切り間際のラストスパートや見積もりの甘さ、マルチタスクによる生産性低下で仕事が終わらないという課題を解消し、意図的に「スラック」を作って安定して納期を守るための実践的フレームワークを提供します。

Core Features & Use Cases

  • 2:8の法則(ロケットスタート):プロジェクトの最初の2割の期間でコア作業の約8割を集中して完了させ、残りの期間を調整・仕上げにあてる。
  • 見積もりと早期検証:受注直後に短期で実作業を試して実測に基づく見積もりを出すことでリスクを早期に発見する。
  • 集中ブロックと流し時間の運用:メール・会議を遮断する「界王拳」集中時間を定義し、午後は流しで付随作業を処理する運用を推奨する。
  • 適用例:短期案件の見積もり検証、長期プロジェクトのフェーズ分割、複数案件並行時の時間ブロック割当、他者遅延に対するモックアップ先行作成。

Quick Start

プロジェクトを受け取ったらまず最初の丸2日(または予定期間の20%)を確保して集中し、そこで得た実測で見積もりを確定し上長へ報告する。

FAQPage Schema
How do I front-load project tasks to finish 80% of the work in the first 20% of the time?

Front-loading task completion requires reserving the initial 20% of your allotted project time for concentrated, no-interruption work blocks to produce early prototypes and measurable estimates. You decompose tasks, establish nightly task lists, and complete core deliverables immediately.

What is the best way to create accurate project estimates for sprint tasks?

The best way to create accurate project estimates is to execute a short burst of actual work immediately after receiving the project, then base your final estimates on those real measurements. This early validation uncovers risks and refines stakeholder communication.

How do I manage concurrent workload and multiple parallel deadlines without losing focus?

Managing concurrent workload requires defining dedicated focus blocks that block emails and meetings, then allocating afternoon periods for processing incidental tasks. You divide time blocks across parallel projects while producing early mockups to handle potential delays from others.

Does this time-management approach work for both individual and team sprint phases?

Yes, this time-management approach works for both individual and team sprint phases. It applies to time-bound work including sprint tasks, project phases, and deadline management, requiring task decomposition and early stakeholder communication through measurable estimates or mockups.

Why does intentionally creating slack time help meet project deadlines?

Intentionally creating slack time helps meet deadlines by finishing 80% of core deliverables in the first 20% of the period, leaving the remaining time for adjustment and finalization. This prevents last-minute rushes and compensates for poor estimates or multitasking drops.
