Bowtie risk analysis

Bowties communicate complex risks with ease.

A bowtie is a diagram that structures risk analysis and communicates risks in an understandable picture. It is used in all high risk industries and is regarded by many as a best practice approach to do risk assessment.


Learn how to build a bowtie and use it in practice. We offer tailor made and public courses from 0.5 to 3 days. Contact us if you want to know more.


Slice can help guide a workshop in the right direction. We have facilitated countless workshops in a variety of industries. This allows us to guide a discussion in the right direction to get to the real issues.


Slice helps you design a risk assessment process that works. Organisations often struggle to set the right context. We develop pragmatic guidelines to ensure a consistent and efficient approach to bowtie.


We use BowTieXP to support the bowtie analysis process and can train a BowTieXP expert inside your organisation. With more than 10 years experience using BowTieXP, we can help with anything related to the software.

Incident analysis

Cut through the noise and learn from incidents more efficiently.

Incident analysis can provide valuable insight in organisational performance if done right. There are a lot of different methodologies, but the best ones make you think one step further and make it easy to communicate the results afterwards. They avoid easy answers and get to the core lessons to be learned. We use barrier based methods like Barrier Failure Analysis because they accomplish all those goals.


Learn how to improve the way you investigate and analyse incidents in practice. We offer tailor made and public courses from 0.5 to 3 days. Contact us if you want to know more.

Incident meta analysis

Creating overview across multiple incidents can be difficult. We offer incident meta analysis, which is done by taking multiple incidents and plotting them onto a common model to see which scenarios keep happening and which barriers keep failing for which reasons.


Slice helps organisations implement effective systems for incident reporting, investigation, analysis and follow up.


We use IncidentXP to analyse incidents and we'll help you do the same. We've used it since the first release, so we can help with anything you might want to know.

Operationalising barriers

Get the right barrier information to the right person at the right time.

One of the problems with risk assessment is that the reports are often forgotten after they're made. To avoid this, ask what you can do after barriers in an organisation have been identified. Slice specialises in operationalising barrier management by making it useful for a person making a decision.


Learn to implement barrier management effectively. We offer tailor made and public courses in barrier management from 0.5 to 3 days. Contact us if you want to know more.

Barrier maturity model

The barrier maturity model allows you to determine where your organisation currently is and see which steps can be taken to mature to a higher level of barrier management. Read more


Implementation can be challenging because it requires tailoring information to the specific needs of a person. Transforming barrier models into something more suitable for operations is where Slice can help.


We use a combination of tools like BowTieServer, AuditXP and BowTieXP to support operational barrier management where needed.

5 reasons why analysing barrier failures is better than 5-why

I hope you'll forgive me, but I don't really like 5-why. It's a decent methodology, but I think there are better options. Instead, we can use barrier-based incident analysis methods. Why is this better? Well, here are 5 reasons why I think analysing barrier failures is better than 5-why.
