商品の多さによるコストは実在し、ほとんど見えにくく、すべてを支えていたサービス業務にのしかかります。 建設・工事業者にとっての問題は一般論とは異なります。サービス業務の粗利益率はプロジェクトの二倍ですが、工期遅延の損害賠償条項に人員を奪われます。売上ではなく、バックログのカバー率とチェンジオーダー捕捉から分析を始めなければ答えは出ません。
商品の多さによるコストは実在し、ほとんど見えにくく、すべてを支えていたサービス業務にのしかかります。 建設・工事業者にとっての問題は一般論とは異なります。サービス業務の粗利益率はプロジェクトの二倍ですが、工期遅延の損害賠償条項に人員を奪われます。売上ではなく、バックログのカバー率とチェンジオーダー捕捉から分析を始めなければ答えは出ません。
工種はそれぞれに理由があって増え続け、削除されることはありません。問題は個別の工種ではなく、全体がもたらす複雑さです。現場要員の割り当て、工種間の切り替え、サポート知識、売上予測の誤差が積み重なります。
そのコストを最も負担するのはサービス業務です。分割された能力がそこに存在するからです。名目上は粗利益に貢献していたプロジェクトを削除しても、全体の利益が増えるケースが少なくありません。
有効な分析は、制約資源に対する貢献度で工種を並べ替え、戦略的な顧客やチャネル要件で残すべきものを特定し、それ以外を切り分けます。
この3つが揃うと特徴的です。1つだけでは別のことを示すことが多いです。
✓ 少数の工種が売上の大部分を生んでいる
✓ 数年以内に廃止した工種がない
✓ 業務の複雑さが売上増加を上回っている
通常、事態を悪化させる対応です。 売上順位だけで末尾を切ることです。負担の軽い工種を失い、現場要員を拘束する工種を残す結果になります。
It is for you if you run or finance a contractor and a minority of lines produces the large majority of revenue. It is the situation where the numbers are available but nobody has put them in an order that produces a decision.
It is not for you if Percision is the wrong tool if you already know the answer and only need execution capacity, or if the business is pre-revenue — then the constraint is evidence about the market, not analysis of your own figures. Percision is not a lawyer, tax advisor, auditor, licensed appraiser, clinical or regulatory filer, or an AI implementation shop. It does not do HR casework, creative-only brand work, or impersonate a named consulting firm. It is a strategy analysis engine — not a template library. Also wrong if you need facilitation, politics, or someone to sit with a lender or buyer. Those are human jobs.

Below is an excerpt from a real run of this analysis on 工事業者. It is a sample profile rather than a customer, and it is engine output translated from English — this is the format you get, on your own numbers.
The subject is Halloway Mechanical, a sample company profile used for testing rather than a customer — $180M revenue, mechanical contracting.
Excerpt from a real Percision run · Customer Value Architecture · sample company profile
The move. Deploy 12 existing journeymen to lock in 40 new hospital service contracts, converting construction relationships into recurring 32% GM revenue.
The leak it closes. Reduces $4.2M overtime drag by re-allocating 12 journeymen from construction backlog to service fleet.
The assumption it rests on. Hospital procurement will accept 12–18% premium pricing for single-source mechanical partner — the engine put the probability at 0.75.
| Investment required | $2M cash (Phase 1); funded by existing $6.4M cash balance. |
| Expected return | 128% gross-profit ROI on $2M investment in Year 1; payback <12 months. |
| Revenue, year 1 | $8M incremental service revenue |
| Revenue, year 2 | $12M cumulative incremental |
| Revenue, year 3 | $18M cumulative incremental |
| Exit criteria | Terminate move if fewer than 15 hospital SLAs signed by Month 9 OR construction backlog falls below 6 months. |

This question routes to Matrix Strategy, one of 29 engagements the platform runs. For 建設・工事業者 it works through job gross margin, backlog cover, change-order capture and service attach rate, then produces the sequence rather than a list of options — which move first, what it funds, and the observation that would say the sequence is wrong.

制約資源に対する貢献度で並べ、戦略的な依存関係を確認します。売上順位だけで判断すると両方向で誤ります。
一部は離れます。事前にリスク金額を算出してください。通常、失う売上より削減できる複雑さのコストの方が大きいですが、それは前提ではなく結果として確認すべきです。
把握されていないため増え続けます。実務的な目安は、売上あたりの営業コストの推移です。売上が増えているのにコスト率が上がる場合、複雑さが主因であることが多いです。
Materially, yes. Service work earns double the margin of projects and loses every staffing argument to liquidated-damages clauses — which changes both the diagnosis and the order of the fixes. The metrics that decide it here are job gross margin, backlog cover, change-order capture, and an answer built on industry-general benchmarks will usually point at the wrong one first.
Less than most people expect. Your last twelve months of revenue and cost split the way you already split it, plus whatever you hold on job gross margin and backlog cover. The analysis is explicit about what it is assuming where your data stops, which is more useful than waiting for numbers you may never have.
