Failure rate

What is the failure rate?

The failure rate of a product is the number of times it is expected to fail in a specified period. This value provides a measure of reliability for a product and helps manufacturers identify areas where improvements need to be made.

Failure rates for startups are incredibly high. Most startups fail within the first year. There are many reasons for this, but one of the main reasons is that they simply don’t have the right team in place. Having the right team is essential for any business, but it’s essential for startups. Without the right team, a startup is likely to fail.

How to calculate the failure rate?

There are two ways to calculate the failure rate of a unit in a system: by using nonlife test units, or by using life test units.

For nonlife test units, the failure rate is represented by a visual Type 5 operator and is always set to 0.

For life test units, the failure rate is calculated according to the type of life test unit being used. The steps for this calculation are as follows:

Step 1: To select the reliability data analysis method of the unit to evaluate the basic failure rate of the life test unit.

For a large sample of the life test unit, their basic failure rates can be evaluated by reliability data analysis of a classical method. However, for a small sample of the life test unit, the basic failure rates should be evaluated by reliability data analysis of the Bayesian method. This is because by taking advantage of its prior information and limited life test data, more accurate results can be achieved.

Step 2: The basic failure rate of a life test unit can be evaluated by reliability data analysis of a classical method. The steps for evaluation are as follows:

1) Determine the total time test according to selected data of the life test unit.

2) Develop the likelihood function according to the test data of the test sample.

3) Obtain the point estimation of the basic failure rate for the life test unit by solving the likelihood equation.

Step 3: To calculate the failure rate of a life test unit, you will need the following:

  • The point estimation of the failure rate for the ith life test unit
  • The correction factor of the ith life test unit, which takes into account time-dependent functions
  • The quality rank coefficient of the ith life test unit
  • The environmental influence coefficient of the ith life test unit

With these values, you can then determine the failure rate of the life test unit.

How to reduce the failure rate?

Though there are no easy solutions, there are ways to improve innovation effectiveness in your company or for your clients. I’m passionate about sharing ten actions to reduce the failure rate of innovation.

Build momentum for your innovation project from the get-go. There needs to be a sense of urgency, otherwise, innovation is considered playtime, and nobody will be prepared to think outside the box. If this is not the case, stimulate other managers to explore your fast-changing environment, wait until they get nervous, and prioritize innovation.

Before beginning your innovation project, it’s essential to have a clear and concise innovation assignment. This will ensure that top management is concrete about the market/target group for which the innovations must be developed and what criteria these new concepts must meet. Even though you may be capable of inventing things on your own, innovation is best done as a team. Not only will this result in better outcomes, but you’ll also gain internal supporters for the innovative outcomes. Make sure to invite people who are personally relevant to the assignment, those who have a say in decision-making, and also a couple of outsiders who are outside-the-box thinkers.

It’s important to design new products and services with the customer in mind. How attractive are the new concepts? You should check their strength among potential customers at the front end of innovation. Use customer feedback to convince your peers that you’re on the right track.

It’s also important to bring business back and substantiate, convincingly and professionally, why and to what degree the new concept can meet all essential financial criteria of your organization.
