Asked Perplexity.com on 28 april 2025:
> Are there sources to support the following claim: "The average employee uses 5-20 apps in their work that are not mandated by the IT dept, and are not behind SSO"
Yes, the search results provide relevant data points to support parts of this claim, though not the exact 5-20 range:
1. **App proliferation**:
- **Average app usage per employee** has risen significantly, with desk workers now using **11 apps** (up from 6 in 2019)[5](https://www.ciodive.com/news/gartner-digital-worker-tools-IT/649844/).
- **Shadow IT prevalence**: Over **one-third of enterprise apps** are classified as shadow IT (non-IT-sanctioned tools)[5](https://www.ciodive.com/news/gartner-digital-worker-tools-IT/649844/), suggesting employees frequently adopt apps without formal approval.
2. **SSO limitations**:
While the search results don’t quantify how many apps lack SSO integration, **Okta’s ecosystem** (a major SSO provider) is mentioned as a common enterprise tool[6](https://www.reddit.com/r/privacy/comments/pzyy17/my_employer_is_forcing_everyone_to_download/). However, the rapid growth in app counts (e.g., **255 apps**for mid-market companies[4](https://chiefmartec.com/2023/04/how-big-is-your-tech-stack-really-heres-the-latest-data/)) implies many tools operate outside centralized authentication systems.
3. **Supporting inferences**:
- **App overload** is explicitly cited as a productivity drain, with employees switching between **13 apps 30 times daily**[3](https://www.ciodive.com/news/app-switching-enterprise-asana-report/594233/).
- **User frustration** with app sprawl (e.g., 26% of workers report inefficiency due to app overload[3](https://www.ciodive.com/news/app-switching-enterprise-asana-report/594233/)) indirectly supports the idea that employees adopt non-mandated tools to fill workflow gaps.
**Conclusion**: The data confirms **rising app usage** and **shadow IT prevalence**, aligning with the claim’s premise. While the exact 5-20 range isn’t directly cited, the growth from 6 to 11 mandated apps[5](https://www.ciodive.com/news/gartner-digital-worker-tools-IT/649844/) and the high shadow IT rate[5](https://www.ciodive.com/news/gartner-digital-worker-tools-IT/649844/) suggest non-mandated app usage likely falls within or exceeds this range. The SSO aspect, though not quantified, is plausible given the scale of app sprawl[4](https://chiefmartec.com/2023/04/how-big-is-your-tech-stack-really-heres-the-latest-data/)[5](https://www.ciodive.com/news/gartner-digital-worker-tools-IT/649844/).
**Key sources**:
- **Gartner**: 11 apps per desk worker[5](https://www.ciodive.com/news/gartner-digital-worker-tools-IT/649844/).
- **Zylo**: 255+ apps in mid-market tech stacks[4](https://chiefmartec.com/2023/04/how-big-is-your-tech-stack-really-heres-the-latest-data/).
- **Asana**: 13-app daily switching[3](https://www.ciodive.com/news/app-switching-enterprise-asana-report/594233/).
