Nope, estimation is tech teams work


Nice analysis. That's how I started except I used the population number to be 10lakh out of which 65% have smartphones and the rest have feature phone.
She cut me out right there saying "do you think everyone in Mumbai have phones?"

Business Analysts (BAs) typically rely on data-driven analysis and evidence-based methodologies to make informed decisions and recommendations. While BAs may need to make estimates or projections in certain situations, such as forecasting future trends or assessing potential outcomes, these estimates are typically based on available data, historical patterns, and statistical modeling techniques.

Guesstimates, on the other hand, are rough approximations or educated guesses that are not necessarily based on rigorous analysis or data. While BAs may use their professional judgment and experience to provide rough estimates in some cases, it is generally preferred to rely on more robust methodologies and data-driven approaches whenever possible.While BAs may occasionally need to provide estimates or projections, they primarily rely on data analysis and evidence-based techniques rather than guesstimates


Yeah but you can't have a healthy discussion when someone's just trying to flex and feed their ego in an interview nonetheless

These kind of questions can be asked in an interview. Usually by product companies. The important point is asking questions, explicitly stating assumptions, and then logically tackling the problem. There can be multiple ways to approach the problem. As long as you have some structure in your approach, it should be fine.

Our offices are closed though we're still in the service industry. I spent 1 hour last week and 1 hour today replying to minor asks and clients were so appreciative - their offices are open. I've build lasting client relationships doing this. There's a way to balance service expectations with boundaries. Noone else on the account even tried. Maybe the art of client service is dead. Thoughts?


As a Checo fan I’m kinda biased but I feel like the last two races showed that he is acclimating to the car development and continues to prove himself as the ideal no.2 driver for Red Bull.

I know there were a lot of folks saying that he was gonna be a liability for Red Bull but I think he’ll continue to be a huge asset even if he isn’t matching Max’s pace


Not a confession, but tomorrow is the second funeral I’m attending in under a year due to someone losing their battle with mental illness.
I know there are certain stigmas with counseling, like “poor people don’t do counseling, we fight” but please get a mental checkup if you start having suicidal thoughts. Even if you feel alone, just know that you have family, friends, neighbors, old acquaintances who would love to hear from you. Pouring one out for my homie.


Hi Ladies - I am about to close out on a purchase of a home (worked for it all by myself; all my money) but unfortunately it’s coming at a time when my spouse is still grieving from the death of a parent. I don’t know how to navigate this. Should I keep him apprised of the home purchase? Should I stay on the down low? Should I ask him how he wants to be involved given that he’s still grieving? Thoughts?

I don’t agree nor do I disagree w/abortion. I don’t have children and still don’t know if I want any, but what I do believe is women should have the choice to make a decision that works best for them and their situation. These constant constraints upon women, that seem to change with changing perspectives, be it women in the domestic realm, women in pants or dresses, AA women in our hairstyles)—should not be decisions left to the court. Cont.


We are short staffed have been for over 6 months, those of us that are left are trying to keep up but we are struggling hard-core. We have had tons of interviews but everyone offered a position (which has been all of them) always says,'oh I have other interviews'. We can't be the only ones dealing with this.
