New Features​

1. [Beta] Anomaly detection

   • We have launched a beta version of anomaly detection for business metrics! Using anomaly detection, customers can quickly identify unexpected increases or decreases in a metric.
   • Anomalies are determined by first calculating the range of expected values for a given metric for each day (or week). The metric value is flagged anomalous for data points where the metric value was outside of the range of expected values.
   • Anomaly Detection is included as part of our Trend Detection analyses. No special configurations needed.
   • Multiple anomalies in a row may mark the beginning of a new trend that may take a few more data points (days or weeks) to be confirmed as a true trend change vs. just an anomaly.

2. [Beta] Unified Workflows for Key Driver Analyses

   • Customers using the “High Accuracy” Top-Driver model can now see statistically-selected “top driver” subgroups alongside all other subgroups, without needing to run two separate analyses to do so. i.e. a unified view of analyses!

   • Subgroups identified as statistically significant Top Drivers are highlighted with a blue indicator, where-as all other subgroups (with lower statistical significance, but some impact to the metric) are shown without this indicator.

   • This feature is presently in Beta. If you would like to give it a try, reach out to your Sisu Customer Success contact.

     

     

3. Global Search — We are introducing Global Search, a simple search bar that lets you search across projects, metrics, dashboards, and analysis from anywhere in the product. Just click on the “search” icon on the left navigation, or press “cmd/ctrl + k” to initiate, and navigate to what you are looking for in one search. To learn more, see the following video: https://www.loom.com/share/3cad750bf655404fbd24ea7e4db90d51

Enhancements​

1. Trend Detection
   • We now automatically default the time filter window to the available date range in your underlying dataset.
   • Any subgroups with a size (i.e., number of rows) greater than 80% are now included in the evaluation of trends. Previously we only looked at those below 80%. This change ensures that even large / obvious subgroups are present in your results for you to evaluate trends and anomalies.
   • For Sum/Count metrics, when clicking on “why did this trend change happen” we now set the data-range for the Key Driver (”Why”) Analyses to be of equal number of days on each side of the trend change date. This ensures that the resulting analyses has even days for each comparison period and is thus more accurate is helping you identify the drivers of the trend change. (Note this issue does not exist for Average/Rate type metrics)
2. Product Experience enhancements
   • Introducing Right Click to Open: Project list, analysis list, and dashboard lists now have a standard right click so you can right click and open the analysis or project or in a new window or a tab, without leaving the original page you are on.
   • Introducing Bulk Delete: You can now delete multiple analysis together and keep your projects clean with the new “bulk delete” feature.
   • Improved Sorting: Project lists sort in the same default order across the app so that you can view the same list and order everywhere.
   • Improved error messages for various data types in the application to give you more context on errors.
   • We have centralized the “metric deletion” to the “metric library” only, so that you do not accidentally delete a metric by mistake from other pages.
   • 90% faster load times of all pages that have a list of tables, queries, or dimensions in them from your data-warehouse!
3. Metric Units & Decimal Places
   • You can now set the units and decimal places for any Metric on the Metric setup page. The units show up on Key Driver Analyses, Trend Detection, and Dashboards, making it easier to consume and understand analyses results.
4. Key Driver Analyses APIs
   • Analyses results now include “impact” for each subgroup in the API response for Key Driver Analyses. With this update, all statistics in the “Top Drivers” table are now included in the API response
5. Updates to pysisu
   • Our python library, pysisu, has been updated. Now you can run analysis with the run() method, allowing customers to embed KDA executions directly within a data pipeline. Impact score has also been added to KDA results to complete the export of all fact table information
6. Predictions [Beta, Invite only]
   • Improved predictions table formatting based on the type of metric the predictions are for.

Bug Fixes​

1. Key Driver Analyses
   • Fixed SQL Server, Big Query and SAP Hana Date Truncations not bucketing days from Monday to Sunday.
   • Gracefully handle connection errors to customer data warehouse for Filter drop-down values
   • Fixed an issue where the “Christmas tree” chart in the Fact Detail Page was broken for percentile bin columns

   • Fixed series and result loading for non-board sliced explorations

New Features​

1. Sisu integration with Looker

   • You can now kick-off a Key Driver Analysis from a Looker Dashboard. This makes it easier to understand “why” your metrics are changing if you use Looker to understand the high-level view of your metric. Sisu automatically creates the metric and analysis based on the measure and dimensions defined in the LookML of the Explore. Video Demo below.

   • Setup Looker integration with Sisu, instructions here

   • Demo Video: Start a Key Driver analyses from Looker:

2. Live Chat for Support

   We now support chat communication inside the Sisu platform for all Support related issues or questions. Click on the help logo (pictured below) to get started and connect with us! We plan to be live 8AM – 4 PM Pacific Time, Monday – Friday with the exclusion of major holidays.

3. New help pages

   We released a new Knowledge Base to provide a cleaner UI and more features to make it easier for you to find the content you need. Check it out here: https://docs.sisudata.com/

   Sisu now supports data connection through SAP Hana.

Feature Enhancements​

1. API Updates API Key Generator in the UI: Users can now generate API keys directly from the UI. See demo below:

2. API Documentation

   Released API documentation here. This makes it easier for users to understand our APIs and build the scripts/apps they need.

3. [Beta] Consume Trend Detection results

   Just like KDA consumption, customers can now consume Trend Detection results via Sisu APIs. See documentation here. (You will need to select Trend Detection analyses on the right panel)

4. [Beta] “PySisu” SDK to consume Sisu API results

   We just released an initial SDK to show Sisu facts in a clean table view. SDKs make it easier for customers to consume Sisu APIs and build the scripts/apps needed to automate ACTIONS from Sisu insights. You can find it here: https://github.com/sisudata/pysisu

5. [Beta] Scripts for exporting Sisu Facts into Snowflake

   Leveraging the Sisu API and Airflow, we now have scripts to help customers export Sisu facts programmatically into Snowflake (other CDWs can be done on request). Find them on Github: https://github.com/sisudata/sisu-airflow

6. Trend Detection

   • Updated chart tooltip to show trend slopes before and after trends change

     

   • Added explicit error handling when no time dimension is selected

     

   • Improved the trend detection algorithm to truncate the number of facts being returned to the web app based on fact quality (determined by various factors such as slope and impact)

7. Dimension name styling

   Updated fact factor styling in Trends and KDAs so that dimension names are easier to read and percentile range details are more concise

8. Easier Navigation

   • It is now possible to filter by “analysis type” on the project’s analysis-list page

     

   • Analysis list navigation dropdown now shows details of the analysis type making it easier to quickly hop to the analyses you need

     

   • Dashboard list can now be sorted by “last run”.

     

   • When you create a new dashboard, it now lands you at the new dashboard, rather than having to navigate yourself.

9. SQL Editors

   • Removed the unsaved “untitled query” from the list of sql queries.

   • Query Preview - now we freeze row headers on top for the table preview.

     

   • SQL Queries in the side panel are now sorted by ‘Last Edited’

10. Admin Settings

    Member role can be changed to Admin from the UI.

Bug Fixes​

We fixed over 30 bugs recently! Here are a few major ones:

1. SQL Editor

   Better error reporting for SQL queries — Customers get the correct line number in which the error occurs when there is an error in the query.

2. Trend Detection

   • When creating a Key Driver Analysis from Trend Detection Analysis, filters are preserved and applied to the new analyses
   • Dynamic filters and summary periods now populate for all trend detection analysis

3. Dashboards

   Fixed dashboard tile resize handle icon (previously was not rendering)

1. [Beta] Trend Detection
   • We increased the speed of running time series stats by 45x.
   • We now support time period aggregations, by day, week, or month
   • Subgroup sizes are now shown on a per-trend basis rather than overall for Trend Detection.
   • Trend analyses now ignore leading zeros in the data
   • Sisu now gracefully handles datasets without data in the analysis period
   • Added custom time filter to replace history length
2. Key Driver Analyses
   • When there are few facts on the Fact Table, we now automatically “ungroup” the facts so you can see them all. Without this, order 2 and 3 facts would be hidden.
   • Filter dropdown values are now sorted numerically or alphabetically and not by how prevalent they are.
3. Dimension Management
   • Dimensions are now sorted alphabetically in both the key driver analysis and time comparison dimension modal, as well as the metric setup page.
   • You can now quickly filter dimensions by data type so you can easily see and find the dimensions that are strings, numbers, booleans or time-stamps.
4. Boards & Embedding
   • Added “Share” link to copy the URL of a board
   • [Beta] You can now pin the time chart from the fact detail page to a board or embed it in Tableau
5. Improving Analyses Run Speed
   • Key driver analysis → Unweighted categorical compares now runs faster for some datasets
   • Enabled native Snowflake unload to Azure
   • Fixed a bug in the ‘compare top driver’ algorithm which improves workflow times for large datasets
6. Project Page
   • Updated analysis tags to show more explicit types: “General performance”, “Trend”, “Time compare”, “Exploration”
7. Metrics Setup
   • Added “select all” and “deselect all” for dimension lists in metric setup
   • Made “duplicate metric” more discoverable in metric setup

1. [Beta] Trend Detection improvements
   • Time grain configurability: You can now examine trends aggregated by day (existing), week, or month
   • Control trend sensitivity: Some data sets have a lot of noise, and some don't. Now you're able to adjust how sensitive you want our trend detection algorithm to behave.
   • Subgroup size calculation: See the size of each subgroup during a trend and not just over the whole data set period. This should help you paint a better picture of just how impactful this subgroup was during a trend.
   • Zero filtering: Missing data for one day/week/month? Trend detection can now ignore “zeros” to more confidently and accurately determine actual trends and trend changes.
2. [Beta] Row Sampling for Key Driver Analyses: You can now run key driver analyses on a sample of your data (e.g. 10% of rows randomly sampled). This improves analyses run time by 2-10x and allows you to quickly iterate on your dimension setup before running on full data.
3. Dynamic time filters for General Performance and Group Comparisons: You can now dynamically filter on time ranges in all key driver analyses (i.e. not just time comparisons). This means you don't have to update their date selection as time progresses (e.g. "Last month"). This makes it easier to enable Auto-Run and starting Following such analyses
4. Verified metrics: You can now toggle a metric as “verified”. With verified on, you know which metrics are the source of truth and worth using (among duplicates or various versions) in order to save time and trust analysis results.
5. App Navigation:
   • In the project analyses list page, you now clearly see which type of key driver analysis was run (e.g., ”Time comparison”). This makes it easier to know what type of analyses you are navigating to.
   • You can create a metric and analyze from within projects. This interaction was available in the data and metrics tab and is now available in the projects tab as well!
6. SQL editor improvements
   • Improved table name view: You can now (A) resize the side pane; to see the ENTIRE_TABLE_NAME_NO_MATTER_HOW_LONG_IT_IS, (B) hover to see the full name (C) click to copy the table name, and (D) see the custom query name or table name of current data preview.
   • Faster typing: We fixed a bug causing a typing lag. Type as fast as you can!
   • Explore a Query: You can now directly open an Exploratory Analyses to explore the results of a SQL query without needing to create a metric first! This makes it easier to do some data exploration for a table before creating metrics for further analyses.
7. Dashboards & Sharing
   • Pin Key Driver Fact Table to Dashboards: You can now pin the Fact Table from the Key Driver Analysis page to a dashboard by clicking a “pin” button, and selecting your favorite dashboard(s).
   • [Beta] Embed Fact Tables in Tableau: You can now embed any Fact Table into Tableau and share the magic of Sisu with Tableau.
