What is a business model? why service may be a good start and why disruptive innovative business model is more important than service or product priorities?
Business model is the central nervous system of running a company whose function is to coordinate all entrepreneurial support systems for the sole purpose of achieving growth strategies where the right customer is willing to pay right price for the right products/services.
Business model is a creative intelligent way of solving your business problem of growth, sustainability, and selling the buy to the consumer; having the greatest product/services alone is not enough. It is not just super marketing strategy. It is also pricing strategy, it is also the product priority strategy; also of segment strategy; also of strategizing timing and priorities of the markets and consumers.
It is often difficult to develop 10-100 million dollar products. Often products as a start-up strategy will lead to likelihoods of loss more often and more quickly. It is much easier to develop a 5-20 million-dollar service company, compared to a 10-100 million product strategy. The bigger the vision to develop, the more prominent are the absolute loss due to product failures.
As to why most products fail, read, https://hbr.org/2011/04/why-most-product-launches-fail
None the less whether product or service, there are so many ways an organization can compete in the market place intelligently using a business model.

The Yin-Yang of Business Models: Discovery Process and Execution for excellence
The importance of business model and the need to be innovating regarding the business model in the market place does not stop even for a well-established company, though it is often identified as a critical success factor as well as a critical lift factor of a strategic KPI of start-ups. With such an approach it is easier to see multi-fold lifts due to innovative disruptive business models among the start-ups.
The yin-yang of business model discovery and business model execution and how to achieve the discovery process quickly is explained by Stefan Gross-Selbeck: Business model innovation. https://www.youtube.com/watch?v=rgufaJ4gjPo
Traditionally, a start-up is different from well established companies.
A start up is trying to get all its support functions working smoothly and contributing to making money; it is at the same time figuring out how to do it efficiently so that it can sustain and grow, even if the margins fall; how to keep the differentiation and uniqueness as a competitive force so that newer competitions do not take away its ability to sustain and growth - Doing all with the focus of making money and at the same time, growing and sustaining in its cycles of daily operations.
A start-up is always trying to figure out its business model; it is on the discovery mode, until it becomes a well-established company where the threat of its existence is not any more a serious problem, but its sustained growth may be its problem.
On the other hand, a well-established company has been filtering out of those situations over time, and it becomes well established; mostly it is trying to optimize the resources, inputs, budget to keep sustainability and growth. A well-established organization has figured it out already, optimized the various components of how they all come together, and it is executing its initial model that sustained and grew into more a successful continuation model, and where possible, continue to keep growth in a modest way for its stake holders.
In a brief one-word comparison, they are two different worlds of focus on what would make it a success, sustain, and become established success. They are discovery vs. execution.
A big problem is not every company can work on both sides, and both are needed. Start-ups or well established companies, if companies were to continue to thrive, grow in the market place, they all have to have the mind-set of a startup, and yet execute on a daily basis. If a well-established company is not facing the disruptive strategic business model from its competition, head-on, it will become irrelevant and loose its market to its competition. So There is a systematic way to have a start-up mindset and execute on a daily basis, and the key functioning characteristics of such a mind-set are:
- Attacker mindset to win
- Agile mindset to win
- Failure is ok mindset to win
So, in essence you may say that it is that the “Discovery” and “Execution” are two parts of yin-yang of business model.
A comparison of product vs. services start-up.
I want to bring out why to choose one over the other before I go for kindling your thoughts on how to execute one over the other with a plan to move from services to product.
We know something is a service (and hence the lack of it as products) when we see the following attributes
For more extensive details on how to identify something as service(and hence something is not a service) here is a list from a reference - reference at the bottom.

Recommender Systems –
“…We compare and evaluate available algorithms and examine their roles in the future developments. In addition to algorithms, physical aspects are described to illustrate macroscopic behavior of recommender systems.
Potential impacts and future directions are discussed. We emphasize that recommendation has a great scientific depth and combines diverse research fields which makes it of interests
for physicists as well as interdisciplinary researchers.

For a detailed executive summary see http://www.mckinsey.com/~/media/McKinsey/Business%20Functions/Business%20Technology/Our%20Insights/Disruptive%20technologies/MGI_Disruptive_technologies_Executive_summary_May2013.ashx
A short meta summary is provided here:
Changes in technologies is always happening due to competitiveness. There is always hope and excitement when a new technology develops and to top it, the business community looks for opportunities to re-adjust their strategies, and reposition their competitiveness in light of the new developments in technologies. There are certain technologies that exhibit early explosive successes indicating potential to change the business structures of the world, enhance the quality of lifestyle of people in 10x type form factor, and bring new significant opportunities in untapped areas, and expands the level playing field for all the segments of the world population. These are considered as disruptive technologies, and in the words of Pete Schumpeter, these lead organizations to “creative destruction” resulting in new industries, new products/services, new production methods, new applications, new lifestyles, bulldozing incumbent businesses with newer ones, resulting in business processes, new business measures, new data, new type of figuring out insights using the new types of data. We have seen early discussions of such topics as big data in the last 6 years. Also, the economic impact of these technologies has the range of most possible certainty of $16.7T to possible maximum value of $33T, over shadowing all the previous impacts of all the developments the history of the world has seen.
In this document McKinsey brings out twelve such disruptive technologies, of which the central technology that in fact builds/supports/empowers all the other 11 technologies, is the “Automation of Knowledge Management”, the one that has the maximum of the most certain value, with an economic value of $5.2T, among a total of certainty value of $16.7. That is close to one third of the most certainty economic value that is possible due to all the other 11 disruptive technologies. The exciting thing is these economic value is realizable in the next 10 years.
This course is uniquely positioned to address the entrepreneurial opportunities that are coming together in the space of data, analytics, and technology, as a platform for knowledge management.
Some key high lights of the knowledge management are:
- This is all made possible because of the enormous computing power achieved in the last 30 years, a 100 fold increase in the sophistication and the variety of applications. The iphone 4c is one such a model compared to the computer used in the Apollo 11 lunar module! This makes it possible in the creation of all types of new data as streams, a continuous flow of data resulting in lots of unstructured data, besides structured data, for which we are yet discover efficient and systematic ways of collecting, analyzing, and applying the insights.
- There will be nearly 230 Million knowledge workers, 9% of the world work force who will be engaged by this disruptive industry
- The economic impact of these 230 million people will cost nearly $9T, which is one fourth of the global employment costs, indicating the importance of HR/people analytics
- This will change the nature of work, creates opportunities for entrepreneurs, help create new products and services, changes organizational structures, changes comparative advantages for nations, affects employment, poses new regulatory and legal changes.
Let us get clarity, explore possibilities, and venture in unexplored areas of opportunities.
Google Maps - How to create any type of GOoGle maps using shape Files... county level choropleth as example. it does address specific application too...
Google maps and Google fusion tables resources are phenomenal. You can create maps with statistical analysis as well as with pin pointed address based identification with images. Somewhat similar tool is Microsoft PowerBI and PowerMap tools. But it requires the latest Office product. You are authorized to get Office365 free due to your studentship with Northwestern University. Go to http://www.it.northwestern.edu/software/microsoft/office365.html and sign in using the right upper corner pull down menu. Choose Work/Schoo/University option. It will allow you to download the full suite of Office365 that includes Excel. PowerBI is an add on. However, this assignment is a showcase using Google maps and Google Fusion tables.
The R language has a long way to catch up with these tools for its ease and the diversity and the pin-pointed levels of detailed works you can accomplish with latest shape files. So, let us go with Google maps.
The assignment is about usage of county level maps, not more detailed than that.
Step1: Identify counties with unemployment rate more than 10%, based on the latest numbers released by Bureau of Labor Statistics for December 2015. (50 points)
The following map is an example of counties with unemployment rate more than 10%. Some parts of Kentucky, Mississippi, California seem to be worst hit, according to the latest, DEC15, unemployment rates by counties. The merged table and the associated map that I created, looks like the one in my blog:
The key learning site you need for your assignment is to use: http://www.poynter.org/2011/how-to-map-data-onto-counties-districts-using-shpescape/141788/ However, attending the special Thursday Sync session (18FEB16) would make this an easier piece to follow.
Download the BLS unemployment rates for December 2015 using the link, http://www.bls.gov/lau/laucntycur14.txt. Download the text file, load it as "|" delimited file into Excel and remove all the other months and save only the DEC-15(P) data to create it as a Fusion table in your google account.
Download the county level shape files from my directory, https://www.google.com/fusiontables/DataSource?docid=1lyYMQJK9nEo8t1oaHZTaZ86_hTUm2POoBQ6pPk28.
Merge both these accounts using the merge details given here, with in your google account. Details of merge processes are given here: https://support.google.com/fusiontables/answer/2571232#play . This link also has details on how to create the map in minutes.
Step2: Create a choropleth map(the second map in my link) using the "change feature styles" on the left navigation panel using all the data, with out any filter (50 points)
