In short

Not invented here (NIH) is a negative attitude toward ideas, technologies or knowledge that come from outside a team or organisation, even when they would be useful. A classic study by Ralph Katz and Thomas Allen (1982) of R&D project groups linked long-tenured teams to falling communication with outside sources and declining performance; Dennis Antons and Frank Piller later mapped the attitudes and decision biases behind it.

How it works

01
Identity forms
Stable teams build pride in their own methods and expertise.
02
Outside contact falls
Over time, members talk less to outside sources of information.
03
External knowledge is discounted
Ideas from competitors, partners or other units are seen as less relevant or less reliable.
04
Costs pile up
The team duplicates work, adopts good ideas late, or misses them altogether.

Where you see it today

Build vs buy in AI

Some companies insist on training their own models when strong open-weight or commercial models already exist. Building can be right for control or cost, but when the main reason is that outside models feel foreign, that is NIH.

Tenure and isolation

Katz and Allen found that project teams’ performance declined after several years together, best explained by falling communication with colleagues and with critical outside sources (Katz and Allen, 1982). Long-running AI and data teams face the same drift.

Internal tool wars

A team that rejects an AI coding or analytics tool because another department chose it shows NIH at small scale. Antons and Piller describe how simply classing knowledge as “external” can trigger its rejection (Antons and Piller, 2015).

Open innovation as the counterweight

Some firms invite outside ideas on purpose. Procter & Gamble’s Connect + Develop programme asks outside innovators to submit technologies against needs the company publishes.

How to spot and avoid it

  • Before any build decision, list the best outside options and score them on the same criteria as the in-house plan.
  • Ask what the outside option lacks in concrete terms, not whether it feels like ours.
  • Rotate people into long-standing teams and set regular contact with outside experts.
  • Reward teams for adopting and adapting good outside work, not only for building new things.
  • Run a short trial of the external tool before ruling it out.
The Business Engineer lens

Open-weight models and AI tooling now improve faster than most internal teams can match, which raises the price of NIH. The Business Engineer frames the real question as where owning the stack creates an advantage and where buying it lets a company move faster.

Frequently asked questions

What is not invented here syndrome?

It is a negative attitude toward ideas or technologies that come from outside a team or company, which leads people to reject or rebuild them even when they are useful.

What did Katz and Allen find?

In a 1982 study of R&D project groups, performance declined as teams stayed together longer, which the authors linked to falling communication with outside sources.

Is building in-house always NIH?

No. Building can be the right choice for control, cost or differentiation. It becomes NIH when the main reason is that the outside option comes from elsewhere.

How do companies counter NIH?

By comparing outside options on equal terms, keeping teams in contact with outside experts, and rewarding adoption of good external work.

The “Not Invented Here” (NIH) syndrome is a prevalent cognitive bias or organizational mindset that occurs when individuals or groups in an organization reject external ideas, solutions, or innovations in favor of their own internal creations. This syndrome can hinder creativity, collaboration, and progress within an organization.

Understanding the NIH Syndrome

Definition of Not Invented Here (NIH) Syndrome

The Not Invented Here syndrome is a cognitive bias or organizational phenomenon in which individuals or groups within an organization show a reluctance to adopt or accept external solutions, ideas, or innovations, preferring to develop their own solutions internally, even if external options are more efficient or effective.

Origins of the Term “Not Invented Here”

The term “Not Invented Here” likely originated in the field of software development, where programmers or development teams were often hesitant to use code or solutions created by others, believing that their own code was superior. Over time, the concept expanded beyond software development to encompass various industries and organizational contexts.

Characteristics of the NIH Syndrome

The NIH syndrome exhibits several characteristic traits:

1. Resistance to External Input

Individuals or teams affected by the NIH syndrome resist external input, ideas, or innovations, even when they have been proven successful elsewhere.

2. Overemphasis on Internal Expertise

There is an overemphasis on the knowledge and expertise of internal personnel, leading to a belief that in-house solutions are always superior to external ones.

3. Inefficiency and Redundancy

Organizations plagued by the NIH syndrome often engage in redundant efforts to recreate solutions that already exist externally. This can result in inefficiency and wasted resources.

4. Lack of Collaboration

The syndrome can hinder collaboration with external partners, vendors, or experts, as internal stakeholders may be hesitant to seek or accept outside assistance.

5. Resistance to Change

The NIH syndrome can contribute to a resistance to change within the organization, as new ideas or practices from external sources are met with skepticism.

Causes of the NIH Syndrome

Several factors contribute to the emergence of the NIH syndrome:

1. Organizational Culture

Organizational culture plays a significant role. A culture that values internal expertise above all else and does not encourage external collaboration is more prone to the NIH syndrome.

2. Ego and Ownership

Individuals or teams may develop a sense of ownership and pride in their work. They may resist external input to maintain control and protect their perceived ownership.

3. Fear of Outsiders

Fear or mistrust of external entities can lead to the NIH syndrome. Some individuals or organizations may view outsiders as a threat or as lacking an understanding of their unique challenges.

4. Past Failures

Negative experiences with external solutions or collaborations in the past can foster reluctance to engage with external ideas or innovations.

5. Cultural or Industry Norms

Certain industries or cultures may have established norms that favor internal development and discourage reliance on external sources.

Consequences of the NIH Syndrome

The NIH syndrome can have detrimental effects on organizations:

1. Stifled Innovation

Organizations may miss out on valuable innovations and ideas because they are fixated on internal solutions.

2. Wasted Resources

Recreating solutions or ideas that already exist externally can result in wasted time, money, and effort.

3. Reduced Competitiveness

The reluctance to embrace external innovations can lead to reduced competitiveness in the market, as competitors may adopt external solutions more rapidly.

4. Decreased Collaboration

The NIH syndrome can hinder collaboration with external partners, limiting opportunities for growth and expansion.

5. Ineffective Problem Solving

Organizations may struggle to effectively address complex problems when they limit themselves to internal expertise and solutions.

Real-World Examples of the NIH Syndrome

The NIH syndrome can be observed in various industries and contexts:

1. Technology and Innovation

In the technology sector, companies may develop their own software or tools for tasks that could be more efficiently solved by existing external solutions. This can result in wasted resources and delayed projects.

2. Healthcare

In healthcare, medical professionals or institutions may be resistant to adopting best practices or treatments developed in other regions or countries, even when they have proven to be effective.

3. Corporate Product Development

Large corporations may resist acquiring smaller, innovative startups or technologies, believing that they can develop similar solutions internally. This can lead to missed opportunities and delays in product development.

4. Government and Public Policy

Government agencies may be hesitant to adopt successful policies or practices from other regions or countries, leading to less effective public policies and services.

5. Manufacturing

Manufacturers may choose to develop their own manufacturing processes or technologies instead of licensing or adopting proven external solutions, resulting in inefficiencies and higher costs.

Strategies to Overcome the NIH Syndrome

Overcoming the NIH syndrome requires a combination of cultural, organizational, and individual changes:

1. Cultural Shift

Foster a culture that values innovation and recognizes the value of external ideas. Encourage employees to seek external input and collaborate with external partners.

2. Leadership Support

Leaders should lead by example and actively promote external collaborations and the acceptance of external solutions.

3. Education and Awareness

Provide training and education to help employees recognize the NIH syndrome and its consequences. Make them aware of the benefits of external collaboration and innovation.

4. Reward External Collaboration

Recognize and reward employees who actively seek and embrace external innovations and ideas.

5. External Partnerships

Actively seek external partnerships and collaborations that can bring new ideas and innovations into the organization.

6. Pilot Programs

Initiate pilot programs that allow the organization to test and evaluate external solutions before committing to full-scale implementation.

7. Feedback and Evaluation

Regularly solicit feedback from employees and stakeholders about the effectiveness of external solutions and their impact on the organization.

8. Open Communication

Encourage open communication channels where employees feel comfortable sharing external ideas and innovations without fear of rejection.

Conclusion

The Not Invented Here (NIH) syndrome represents a significant challenge in organizations where internal solutions are favored over external ideas or innovations. Overcoming this syndrome requires a cultural shift, leadership support, and a commitment to valuing external input and collaboration. By recognizing the value of external solutions and actively seeking innovation from a variety of sources, organizations can foster a culture of openness and creativity that leads to greater success and competitiveness in today’s rapidly changing world.
