Necessary vs Required – A Complete Comparison

Key Takeaways

• Necessary indicates what is indispensable without which something cannot function or exist.
• Required emphasizes formal obligations or conditions that must be met, in rules or standards.
• The difference lies in necessity versus obligation, with Necessary being more about essential qualities and Required about mandates.
• Understanding the context helps to decide whether something is Necessary or Required for a particular situation.
• Both terms are used interchangeably but have subtle distinctions influencing their application in language and decision making.

What is Necessary?

Necessary refers to something that is absolutely needed for a purpose or outcome, without which it cannot be achieved. It is about essential elements that are fundamental for existence or success.

Fundamental Conditions

Necessary conditions are the core requirements that must be present for a process to happen. Without these, the process simply cannot occur, making them non-negotiable.

Innate Qualities

Necessary qualities are inherent traits that define or characterize something or someone. These are not optional, but integral to the identity or function of the subject.

Basic Needs in Society

Basic needs like food, water, and shelter are considered necessary for human survival. Their absence leads to hardship or failure to sustain life.

Essential for Achievements

In project planning, necessary tasks are those without which the goal cannot be reached. They are the backbone of the entire effort.

What is Required?

Required refers to something that is mandated or stipulated as a condition that must be satisfied, by rules, laws, or standards. It implies an obligation rather than an intrinsic need.

Legal or Formal Mandates

Requirements are set by authorities or regulations that organizations or individuals must fulfill. Failing to meet these can lead to penalties or rejection.

Specifications and Standards

Required specifications define the exact criteria that products, services, or processes must meet. These are documented in technical or operational documents,

Obligations in Contracts

In agreements, required actions are those parties are legally bound to perform. Although incomplete. These obligations ensure commitments are honored.

Prerequisite Conditions

Some conditions are required before proceeding to the next step in a process. They are necessary to ensure proper flow or compliance.

Comparison Table

Below are a detailed comparison of aspects distinguishing Necessary from Required in real-world contexts:

Aspect	Necessary	Required
Source of demand	Intrinsic needs, natural qualities	External rules, regulations
Flexibility	Less flexible, unavoidable	More flexible, can be negotiated or waived
Context usage	Personal, philosophical, or essential contexts	Legal, procedural, or formal contexts
Implication	Status of being vital for existence or success	Obligation to meet standards or rules
Enforcement	Not necessarily enforced, based on necessity	Often enforced by laws or policies
Nature of requirement	Inherent or natural	Imposed or stipulated
Scope	Broader, affecting fundamental aspects	Narrower, specific to rules or conditions
Examples	Necessary nutrients, necessary skills	Required forms, required courses
Impact of absence	Leads to failure or inability to function	Leads to non-compliance or rejection
Relation to standards	Less about formal standards, more about core needs	Directly linked to compliance standards
Subjectivity	Often subjective, based on context	Objectively defined by rules or criteria
Time sensitivity	Often timeless, essential at any point	Time-specific, tied to deadlines or conditions

Key Differences

• Origin of Requirement is clearly visible in Necessary being driven by intrinsic needs, while Required stems from external mandates or rules.
• Flexibility Level revolves around Necessary being less adaptable, as he is fundamental, whereas Required can sometimes be waived or adjusted based on circumstances.
• Context Application is noticeable when Necessary applies more to core qualities or essentials, while Required is used in formal settings like contracts or regulations.
• Enforcement relates to Necessary not being enforced, but Required is backed by legal or official authority.
