Are people during exit surveys more honest in their responses than in engagement surveys?
It is quite common to encounter the opinion that responses in exit surveys or interviews are more honest than those in regular engagement surveys, despite their anonymity and/or confidentiality, especially when it comes to more politically sensitive topics such as satisfaction with one's direct manager. It is usually argued that people no longer fear repercussions or negative consequences for speaking openly about their real experiences and opinions because they leave the organization and have less incentive to conceal critical feedback. Let's see if we can find any evidence of it in the data...

Does a stick work?
Probably each of us has experienced, or at least heard of, the practice of using job insecurity as a motivational tool at some point in our careers. A well-known example of this is stack-ranking performance reviews, where bonuses are given to top performers and those at the bottom are let go. While we may not personally like this method of motivation, it would be beneficial to have some data on its effectiveness.

Embedding R (or Python) ML models in Power BI dashboards
In my new job, we currently rely a lot on Power BI when presenting people-related insights to our stakeholders. Since I know Power BI quite superficially and we also want to share insights from more complex analyses with our stakeholders, I spent part of the weekend studying how to incorporate ML models created in R or Python into Power BI dashboards. I put my learnings in this blog post. It's definitely not rocket science, but it may still shorten the learning path for some of you who are in a similar situation.

Some resources on staff retention and downsizing

Evidence-based interventions that help reduce the gender pay gap
Pay inequality between men and women is not only an ethical and legal issue for companies, but also a marketing issue - it can have a negative impact on their "employer brand" and attractiveness as an employer. This means that if companies want to attract and retain talented employees, they must be able to ensure that they treat men and women equally in this respect. Let's look at what the existing evidence tells us about what might help us with this.
It's perfectly normal not to be normal

Standard vs. trend predictors
When modeling a phenomenon, one usually can't get by with just raw data but must use one's domain knowledge to select and transform the most relevant variables from raw data to be able to successfully grasp regularities in the domain of one's interest. Let's look at one simple example of such feature engineering from the domain of collaboration analytics.

Firemní audit rozdílu mezi platy mužů a žen
Platová nerovnost mezi muži a ženami není pro firmy jen záležitostí etickou a právní, ale také marketingovou - může mít totiž negativní dopad na jejich "employer brand" a atraktivitu coby zaměstnavatele. To znamená, že pokud firmy chtějí přilákat a také si udržet talentované zaměstnance, musí být schopny zajistit, že se u nich s muži a ženami bude v tomto ohledu zacházet stejně. Prvním krokem k tomu je zjistit, jak velký je rozdíl mezi platy mužů a žen ve firmě a do jaké míry ho lze vysvětlit jinými faktory než je samotné pohlaví zaměstnance. V tomto článku demonstruji, jak takovou analýzu provést s pomocí analytického nástroje R a dat, která má většina firem běžně k dispozici. Stručně se zmiňuji rovněž o tom, jaké mohou být případné další kroky a doporučení vyplývající z výsledků provedné analýzy.

HR analytika a odchodovost zaměstnanců
Které faktory přispívají k odchodovosti zaměstnanců a u kterých konkrétních zaměstnanců je zvýšené riziko, že firmu během několika příštích měsíců opustí? Na tyto otázky se čím dál tím více firem snaží odpovědět pomocí analýzy dat o svých vlastních zaměstnancích. V tomto článku se prostřednictvím analytického nástroje R a vizualizačního nástroje Shiny podíváme, jak může být tento druh HR analytického projektu pro firmy užitečný.
Moneyball v HR
Přes popularitu tématu HR analytiky mezi HR profesionály je stále relativně málo společností, které HR analytiku reálně a systematicky využívají. Jednou z možných příčin je to, že tradiční HR mnohdy postrádá analytický mindset a některé z kompetencí, které jsou klíčové pro úspěšnou realizaci HR analytických projektů. V takové situaci může být užitečné podívat se ve větším detailu na celkovou logiku i na konkrétní analytické kroky nějakého úspěšného příkladu využití HR analytiky k optimalizaci některého z HR procesů s pozitivním dopadem na obchodní výsledky společnosti. V tomto článku se tímto způsobem podíváme na známý příběh oaklandského baseballového týmu "Áček", jehož management poměrně radikálně - a podle všeho i úspěšně - přehodnotil svůj dosavadní přístup k výběru nových hráčů na základě výstupů statistické analýzy sabermetrických dat o herním chování hráčů. Využijeme při tom volně dostupný statistický software R a veřejně dostupnou databázi historických údajů o výsledcích v americké baseballové lize.
