Ataytis Assurance
Fault trees, bow-ties, event trees, reliability block diagrams, Goal Structuring Notation (GSN) arguments and Markov models, drawn from the rows in your report and checked against the rules of each method. Whether the work is reliability, safety, risk or assurance, nothing is drawn by hand: change a slicer and the diagram is rebuilt.
30-day free trial. Licensed and billed through Microsoft Marketplace.
Analysis modes
Six analysis modes. One Power BI visual.
Pick the mode your work calls for, from reliability and safety to risk and assurance. Each has its own symbols, rules and settings, all in the same visual and under the same licence.
Fault Tree Analysis
How could this top event happen?
A top event developed through AND, OR, voting and other gates down to basic events.
Explore fault treesBow-Tie Risk Analysis
What can go wrong, what prevents it, and what limits the consequences?
Threats, barriers and consequences either side of a top event, with escalation factors.
Explore bow-tiesEvent Tree Analysis
What follows an initiating event, and how often?
Success and failure branches out to every outcome, with sequence frequencies worked out.
Explore event treesReliability Block Diagram
Does the system keep working when parts of it fail?
Series, parallel, standby and m-out-of-n structures, from input to output.
Explore reliability block diagramsGoal Structuring Notation
Does the argument for a claim hold together?
Goals, strategies, solutions and context for safety and assurance cases.
Explore goal structuresMarkov State Diagram
How does a system move between states over time?
States and the transitions between them, with rates, probabilities and repairs.

From a table to a diagram
Drop the columns from your register, asset list or argument table into the visual and the diagram draws itself. Each row names a node and the node it connects to; the layout, the symbols and the connections are worked out for you. Change a slicer and the diagram is rebuilt from the rows that remain.
Fault trees that follow the logic
Fault Tree Analysis (FTA) drawn the IEC 61025 way: top events, gates and basic events, with AND, OR, voting and priority gates, probabilities under each event, and status colours from your own rules. Collapse a branch to review the rest, and follow a transfer straight to the tree it points to.
Bow-ties from a barrier register or an edge list
Threats on the left, consequences on the right, the top event in the middle and every preventive and recovery barrier in between. Point it at a barrier register with Threat, Barrier and Consequence columns and the bow-tie is built for you, with a count of barrier status above it whenever you want one.
Event trees with the sums done
Event Tree Analysis (ETA) from an initiating event through each function, success above and failure below, out to every outcome. Give it branch probabilities and an initiating frequency, and every sequence gets its identifier, path probability and frequency, written where the sequence ends.
Reliability block diagrams, series to 2-out-of-3
Reliability Block Diagrams (RBD) with series paths, parallel redundancy, m-out-of-n voting, standby components and switches, drawn from input to output. Switch between the IEC 61078 look and your own with one setting, and the structure stays exactly as it was.
Safety and assurance cases in Goal Structuring Notation
Goal Structuring Notation (GSN) laid out as a goal structure: goals, strategies, solutions and their context, checked against the connections the GSN Community Standard permits. Decorators such as undeveloped, optional and choice are drawn with their marks, and anything joined the wrong way is flagged before a reviewer finds it.
Markov models you can read at a glance
Markov state diagrams, the state transition diagrams of a Markov chain: states laid out as a progression, a transition and its return drawn as a pair, every transition carrying its rate and every state its probability, in the format you set in Power BI. Draw states as circles or boxes, with the IEC 61165:2006 profile or your own look.
Click a node for the whole picture
Clicking a node filters the rest of the report to every row behind it and opens the Node Inspector: its values, its details, links to its documents, and every related node a click away. You choose which columns it shows, in what order and under which headings, and Focus branch fades everything else so a review can follow one path.
One editor for all of it
Mapping, layout, notation, colours, labels and interactions live in one editor with a live preview of your data. The Validation tab checks the diagram against the method as you go, and each analysis mode keeps its own settings, so switching never undoes your work.
Why it is different
Built to sit in a real report
Not a widget bolted onto the page — a visual that reads your data, follows your styling, and answers to your filters.
Build in Desktop with no licence
Power BI Desktop runs the full visual with no licence, no watermark and no sign-up, so a diagram can be built and reviewed on your own data before anyone pays. A licence is needed once the report is published to the Service for others to open.
Checked against the method
Each analysis mode runs its own rules: a gate with too few inputs, a threat with no path to the top event, a Goal Structuring Notation connection the standard does not permit, an absorbing state with a way out. The Validation tab says what is wrong and where.
Columns that map themselves
Columns named the way engineering tables usually name them, such as Node ID, Parent ID, Node Type, Label and Probability, bind to their roles automatically. Anything else is mapped once on the Data Mapping tab.
Event tree sequences worked out
Give branch probabilities and an initiating frequency, and every sequence gets its identifier, path probability and frequency, ready to read at the outcome.
Many diagrams from one table
A Diagram ID column turns one table into several diagrams, with a picker to move between them. Fault tree transfers open the diagram they point to.
You decide what a click shows
Columns in Data fields appear under Details, columns in Values under Metrics, and columns in Tooltips on hover as well as under Details. Rename any heading, such as Metrics to Engineering, and hide or reorder single fields.
Colour rules and a legend that match
Conditional formatting colours nodes and connectors from any value on the diagram, such as Status or Probability. The legend is built from the same rules, so the key always matches the drawing.
Big diagrams stay usable
Search, zoom, fit to view, a minimap, and expand and collapse on any branch. The keyboard moves between nodes, and every node has an accessible name.
Your numbers in your formats
Tooltips, the Node Inspector and value annotations use each column's Power BI format, so a probability formatted as a percentage reads as one.
Certified and self-contained
Microsoft-certified, with no outbound network requests of any kind. Report data is read and drawn inside Power BI, and the visual can be used in tenants restricted to certified visuals.
The full technical detail lives in the documentation.
Getting started
From install to published report
Install once, then it is there every time you build a report.
Install from Marketplace
In Power BI Desktop, open Get more visuals, search for Ataytis Assurance, and add it. The visual is saved in the report, so nobody who opens it has to install anything.
Add your data
Put the columns that name each node, the node it connects to and its type in Data fields. Conventional column names map themselves.
Pick an analysis mode
Select the visual, choose Edit, and pick one of the six. The Validation tab tells you if the table is missing something the method needs.
Licence it to publish
Power BI Desktop runs the full visual with no licence and no watermark. A licence is needed once the report goes to the Power BI Service for other people to open. Thirty days free, billed by Microsoft.
Pricing
Priced per user, with volume discounts
A licence is per user. Everyone who opens a published report containing Ataytis Assurance in the Power BI Service needs one; Power BI Desktop needs none. The first month is free on every plan.
