Maintaining QCD Tactfully: The Way of Inashi #4 — Inner Conviction, Outer Art

Chapter 3: Facing Doubts and as a Technique for "Judgment Timing"

3.1 Designing Requirements and Priorities — Deciding "To Do or Not to Do" Through Structure

The ultimate effectiveness of "Inashi" (the art of deflection) manifests in how to organize additional requirements and where to draw the line.
Will you do it, or not?
If you do it, when and at what priority?
── Whether you can organize this judgment as a structure determines the success or failure on the ground.

The core of this judgment criterion is QCD (Quality, Cost, Delivery).
That is, the three perspectives of: to what extent functions are realized (Quality), how much budget and man-hours can be secured (Cost),
and by when it will be finished (Delivery).

When receiving an additional requirement, first examine it against these three axes of QCD.

• Quality: Does that request truly enhance functional value?
• Cost: Is it worth the cost and risk of adding it?
• Delivery: Can it be implemented without disrupting the schedule?

This cannot be judged in an instant.
That is exactly why "Inashi" becomes a word for "reconstruction rather than immediate decision."

The criteria for requirement organization can be more specifically summarized as follows:

Axis	Content	Remarks
🎯 Purpose Axis	To what extent the requirement contributes to project goals	Differences in perception easily arise between stakeholders
🧭 QCD Axis	Where to balance Quality (function), Cost (budget), and Delivery (timing)	The realistic standard that forms the center of judgment
🕒 Time Axis	Whether it should be done now or can wait until the next phase	Conflict is easier to avoid when priorities are segmented by "time"

In many workplaces, requirements from stakeholders (customers/management) and requirements from those in charge (design/development) exist with different weights.
In such cases, Inashi is neither a "rejection" nor an "acceptance," but rather a linguistic technique for:

“Deconstructing requirements and redefining which axis to handle them on.”

For example, the following organization works effectively:

Situation	Direction of Judgment	Response Example
Low alignment with purpose, large impact range	Postpone (Not Now)	"Let's reconsider this for the next phase."
High alignment with purpose, but difficult timing	Defer (Later)	"It's out of scope this time, but we'll include it as a candidate for the next round."
Alignment in Purpose and all QCD factors	Respond (Now)	"Let's readjust priorities and incorporate it."

Inashi is also a technique for replacing requirements with a "now or later" timeline and making decisions without friction while maintaining QCD consistency.
With this perspective, you can elevate the situation from a simple "accept or refuse" to a structural judgment of "what is the optimal timing and condition to handle this."

"Inashi" is the technique of conveying "not now" in an affirmative form.

3.2 🎯 The Essence of "Inashi" as a Response Technique

"Inashi" is a technique that protects the flow of dialogue and relationships, not by rejecting requests, but by avoiding responding to them head-on.
When you must balance the conflicting goals of realizing requests for improvement and completing the project, Inashi is useful.

But at the same time, "Inashi" is a technique that is always adjacent to the question: "Is this just procrastinating on a decision?"

3.3 💭 "Doubt" and "Value" as a Technique

Inashi avoids breaking the atmosphere and avoids conflict.
However, if it becomes a mere "escape," it will result in leaving problems behind and passing the burden to later processes.

That is exactly why "Inashi" requires a design awareness of "intentionally putting a decision on hold,"
without which it becomes indistinguishable from a mere vague response.

• ✅ Why is "not deciding right here, right now" necessary for the project?
• ✅ Why does "saving the other person's face" produce a structural effect?

When you can have your own design intention for these questions, "Inashi" becomes a technique for "judgment timing."

"A good response is one that considers the other party, does not compromise one's own judgment, and protects the project's direction. Inashi is a 'linguistic design technique' for aligning those three."

3.4 🛠 The Value of Inashi in Practical Design (Reprint)

Perspective	Role of Inashi
🗓 Progress Management	To protect the assumed schedule and budget, maintain a consistent flow without immediately incorporating all additional requests.
📦 Scope Control	Functions as a structural design technique to pick up only the bare minimum based on design objectives and priorities, rather than a total rejection of requests.
🤝 Relationship Maintenance	Establishes a response without causing dissatisfaction, opposition, or conflict through a "shift in flow" rather than rejection.
💰 Cost Handling	While maintaining consistency by not accepting immediately, it enables connection to formal handling by clearly stating costs and procedures when necessary.
⚙️ Judgment Structure Operation	Demonstrates response design capability to organize flow, relationships, and design structure without explicitly stating a judgment.

Inashi is a quiet design technique for protecting the structure without stopping the field.

Conclusion: What is the Way of Inashi?

As we have seen so far—

• Inashi is a technique for conveying "not now" in an affirmative form,
• Inashi is a technique that includes questions, sitting alongside the hesitation of judgment,
• Inashi is a "linguistic design technique" for aligning the three parties,
• And, it is a quiet design technique for protecting the structure without stopping the field.

Summing them up—
Inashi is—to protect the customer and ourselves, and to lead the project to success—

Both a belief and a craft.

— Belief within, craft without.
