Is There Anything Wrong with Year 2016

The pop king Prince has passed yesterday at age of 57. He joined a seemingly long list of celebrities we lost this year. Posts on social media go along the lines of "2016 did it again", "First Bowie now Prince" and "Isn't is the worst year ever?". One might really think there is something going on this year. But is it really?

Sunken Costs and Sausages

Last week I went to a client conveniently located in a fantastic tourist destination and I had great opportunity to add some weight while having good times. I was recommended a restaurant serving fantastic one-in-the-world sausages and one evening I took the walk to get there. It was bit off the tourist and business tracks and soon I got to a part of the city where nothing much was happening and I was expecting a quiet and tasty dinner. However, to my surprise the restaurant was crowded as an Apple store on a release of a new iPhone! People were standing with a beverage and plate of sausage so close to each other that even basic activities as checking Facebook seemed impossible. My companions were all "See how good is this place!". But was it really the food that kept people in?

The Problem with Excel Spreadsheets in Organizations

The death of Excel has been announced many times but it seems to be tougher than officer McClane and still saves the day for many organizations. However, implementation is riddled with problems and dangers that could have detrimental effect on careers or businesses. I have long developed and fought for standards and procedures to minimize the risks and pains coming from badly placed, designed and developed spreadsheets and I am not alone in that as there are numerous evangelists of good Excel practices. However, their impact is limited and there are larger opposing forces at play. They come from the organizations and the accessibility of Excel itself.

Quantitative Models in Business War Games

Many things look very cool but turn out to be not that exciting when one try using them. Like voice-recognition technology or Communism or electric cars.

War games in business is simulation of moves and counter-moves by opponents in a commercial setting according to Wikipedia and is a part of the large family of exercises that aim at leveling up the strategies and management methods in modern companies. In a gist, a war game has two or more teams competing for some resources - usually it is a market share, sales or other tangible outcomes. These exercises could be very beneficial for a company. In the general case there is no measure for the impact of a strategy and some thought introducing a suitable quantitative model to deal with that. And it is a good idea. Except it is not as it usually does not work.

From Start up to F**k up - What I Have Learned

I wonder when and why startup businesses became such a big thing. Maybe with the easy access to high tech, available funding and more people got convinced they could develop their own product to kill the market and buy the Hollywood life. However, despite all the books and gurus on the matter, starting a company from scratch is bit more difficult than installing an app on your phone. I am not a doctor but you can trust me on that - year and half ago I co-founded a company and went though the almost full specter of problems and emotions that come with it. The company is focused on retail analytical services and providing BI solution that addresses the specific challenges in that industry. I have recently terminated my tenure there and have the time to reflect and share some of the lessons I took. After all, isn't it a crime if you are in a startup and the world does not know about that?
