This CEO quit his job to become an eco-entrepreneur

A year ago when V Ramesh was 48, an age when high-fliers look for the glorious last lap before reaching the age of retirement, he was bit by the entrepreneurial bug. He called it quits as the CEO of a non-banking finance company to pursue his eco-friendly passion.

After slogging over his bicycle-on-share concept for the last one year Ramesh, an IIM-Bangalore graduate, has finally introduced FreMo (freedom to move; http://www.fremo.in/) India's [ Images ] first state-of-the-art bicycle sharing programme. The project envisages helping the commuters cover the first and last mile of their daily travel to the railway station or bus stop.

"Every day about 7 lakh people come to Thane (a distant suburb on the outskirts of Mumbai [ Images ]) railway station from different parts of the city. They come by cars, motorcycles, buses and auto rickshaws. However, a lot of time is wasted as people keep waiting endlessly for an auto rickshaw or a bus to ply them to their destination. Besides the traffic congestion makes it worse," says Ramesh. He said that his programme intends to give relief to the commuters who want to opt for an economical, eco-friendly and healthy ride.

Ramesh feels the word sharing is a misnomer as it implies something that comes for free. "I also don't want to use the word rental as people have a very different idea about rentals. Though bicycle rental no longer exists in the city, it implies that the vehicle had to be surrendered from the place where it had been hired. Thus there is no concept of freedom in the rental system," said Ramesh.

He clarifies that 'sharing' does not mean 'free' but compared to other modes of transport it is more economical. As per Ramesh's estimates bicycle ride will enable the members to make a saving of Rs 30 to 40 a day on travel expenses.

What Ramesh is offering is brand new unisex bicycles along with lock, helmet, bag and raincoat (during monsoon) that could be picked up from any of its five depots and similarly deposited at any of its five depots. The cycles carry radio frequency tags and members have smart cards containing the information of time of delivery, identity of the cycle and mention other accessories being taken.

The membership process is similar to the mobile service providers -- choose the plan, make payment and submit documents. The payment is also similar to mobile service providers with only the pre-paid option available.

Owning a bicycle, explained the entrepreneur, comes with the responsibility of maintaining it regularly. "Regular maintenance of bicycles is a big dampener for its owners. Often bicycles are seen rotting in and around the buildings," said Ramesh.

Mandar Datar, a businessman who has his office at Kalwa in Thane, says he was unable to maintain his two bicycles that were used by his office boys for running errands.

"FreMo had opened its depot near my office and I enquired out of curiosity. Maintenance of bicycles was a problem and hence opted for this scheme on a trial. It is almost two months and everything is running smoothly," said Datar who is glad that he opted for FreMo.

It is not just businessmen who are getting the bicycles for their staff. Ramesh says that some of his members own cars and motorcycles. After his voluntary retirement from the banking sector Shekar Swaminathan (56), a health conscious person, alternates between walking and cycling on the picturesque Yeoor Hills. "Besides using the cycle for exercise I also use it to commute the 3 km distance between my residence and Thane railway station. Getting on public transport is difficult and so is driving a car. So this is the most sensible way to commute to the railway station," said Swaminathan.

Though he had initially intended to start 40 locations across Mumbai and Thane, availability of funding limited the programme to Thane.

"As a CEO of stock broking servicing corporate clients I was dealing in voluminous amounts of money and Rs 2 crore envisaged for my project seemed like cakewalk to me," said Ramesh. To raise the money was easier said than done. Ramesh finally got his funding from Bank of Baroda

What is lean

Lean manufacturing was developed by the Japanese automotive industry, with a lead from Toyota and utilising the Toyota Production System (TPS), following the challenge to re-build the Japanese economy after World War II.

The concept of lean thinking was introduced to the Western world in 1991 by the book “The Machine That Changed the World” written by Womack, Jones, and Roos.
Lean is a philosophy that seeks to eliminate waste in all aspects of a firm’s production activities: human relations, vendor relations, technology, and the management of materials and inventory.

How does Lean work?
Considers an ‘end to end’ value stream that delivers competitive advantage
Seeks fast flexible flow
Eliminates/prevents waste (Muda)
Extends the Toyota Production System (TPS)

Who is Lean applicable to?

Lean is principally associated with manufacturing industries but can be equally applicable to both service and administration processes
Currently it is also being adopted by the food manufacturing and meat processing sectors
It’s not a new phenomenon, Japanese auto manufacturers have been developing Lean for over 50 years

5 principles of Lean
Value - specify what creates value from the customer’s perspective.
The value stream – identify all the steps along the process chain.
Flow - make the value process flow.
Pull - make only what is needed by the customer (short term response to the customer’s rate of demand).
Perfection - strive for perfection by continually attempting to produce exactly what the customer wants.

value
Any process that the customer would be prepared to pay for that adds value to the product.
The customer defines the value of product in a lean supply chain.
Value-adding activities transform the product closer to what the customer actually wants.
An activity that does not add value is considered to be waste.

The value stream
The value stream is the sequence of processes from raw material to the customer that create value.
The value stream can include the complete supply chain.
Value stream mapping is an integral aspect of Lean.

Flow
Using one piece flow by linking of all the activities and processes into the most efficient combinations to maximize value-added content while minimizing waste
The waiting time of work in progress between processes is eliminated, hence adding value more quickly

Pull
Pull = response to the customer’s rate of demand i.e. the actual customer demand that drives the supply chain.
Based on a supply chain view from downstream to upstream activities where nothing is produced by the upstream supplier until the downstream customer signals a need.

Perfection
The journey of continuous improvement
Producing exactly what the customer wants, exactly when, economically
Perfection is an aspiration, anything and everything is able to be improved

The Cornerstone of Lean – Toyota Production System
Based on two philosophies:
1. Elimination of waste
2. Respect for people

Toyota Production System’s Four Rules
All work shall be highly specified as to content, sequence, timing, and outcome
Every customer-supplier connection must be direct, and there must be an unambiguous yes-or-no way to send requests and receive responses
The pathway for every product and service must be simple and direct
Any improvement must be made in accordance with the scientific method, under the guidance of a teacher, at the lowest possible level in the organization

Taiichi Ohno’s 7 Wastes (muda)
Types of waste
Overproduction
Waiting time
Transport
Process
Inventory
Motion
Defective goods

7 Service Wastes
Delay – customers waiting for service
Duplication – having to re-enter data, repeat details etc
Unnecessary movement - poor ergonomics in the service encounter
Unclear communication – having to seek clarification, confusion over use of product/service
Incorrect inventory – out of stock
Opportunity lost – to retain or win customers
Errors – in the transaction, lost/damaged goods

The 5S‘s
The 5S‘s are simple but effective methods to organise the workplace
The methodology does however, go beyond this simple concept, and is concerned with making orderly and standardized operations the norm, rather than the exception
Posters bearing the 5S terms can be found on the walls of Japanese plants, and are a visual aid to organisational management

Seiri Sort
This requires the classifying of items into two categories, necessary and unnecessary, and disregarding or removing the latter.
Seiton Straighten
Once Seiri has been carried out Seiton is implemented to classify by use, and arrange items to minimise search time and effort. The items left should have a designated area, with specified maximum levels of inventory for that area.

Seison Shine
Seison means cleaning the working environment. It can help in the spotting of potential problems as well as reducing the risk of fire/injury by cleaning away the potential causes of accidents.
Seiketsu Systematise
Seiketsu means keeping one's person clean, by such means as wearing proper working clothes, safety glasses, gloves and shoes, as well as maintaining a clean healthy working environment. It can also be viewed as the continuation of the work carried out in Seiri, Seiton, and Seison.
Shitsuke Sustain
Shitsuke means self-discipline.
The 5 S‘s may be viewed as a philosophy, with employees following established and agreed upon rules at each step. By the time they arrive at Shitsuke they will have developed the discipline to follow the 5 S‘s in their daily work.

SOCIAL SCIENCES AS A CAREER

By


- Sudhakar Kumar Mishra

Social sciences study all aspects of society—from past events and achievements to human behavior and relationships among groups. Their research provides insights that help us understand different ways in which individuals and groups make decisions, exercise power, and respond to change. Through their studies and analyses, social scientists suggest solutions to social, business, personal, governmental, and environmental problems.
Research is a major activity of many social scientists, who use a variety of methods to assemble facts and construct theories. Applied Research is designed to produce information that will enable people to make better decisions or manage their affairs more effectively. Collecting information takes many forms, including interviews and questionnaires to gather demographic and opinion data; living and working among the population being studied; performing field investigations; analysing historical records and documents; and preparing and interpreting maps and computer graphics. The work of specialists in social science varies greatly, although specialists in one field may find that their research overlaps work being conducted in another discipline.

Nature of the Work

The major social science occupations include political scientists, sociologists, anthropologists, archaeologists, geographers, and historians. The scope of work of each of these professions is dealt with in detail below.

Political Scientists study the origin, development, and operation of political systems and public policy. They conduct research on a wide range of subjects, such as relations between India and other countries, the institutions and political life of nations, the politics of small towns or a major metropolis, and the decisions of the Court. Studying topics such as public opinion, political decision making, ideology, and public policy, they analyse the structure and operations of governments, as well as various political entities. A political scientist might conduct a public-opinion survey, analyse election results or public documents, or interview public officials.

Sociologists study society and social behavior by examining the groups and social institutions people form, as well as various social, religious, political, and business organizations. They also study the behavior of, and interaction among, groups, trace their origin and growth, and analyze the influence of group activities on individual members. Sociologists are concerned with the characteristics of social groups, organizations, and institutions, the ways individuals are affected by each other and by the groups to which they belong and the effect of social traits such as gender, age, or race on a person’s daily life. The results of sociological research aid educators, lawmakers, administrators, and others who are interested in resolving social problems and formulating public policy.

Most sociologists work in one or more specialties, such as social organization,education,the family, social psychology, urban, rural, political and comparative sociology; gender relations, criminology and sociological practice.

Anthropologists study the origin and the physical, social, and cultural development and behavior of humans. They may examine the way of life, archaeological remains, language, or physical characteristics of people in various parts of the world. Some compare the customs, values, and social patterns of different cultures. Anthropologists usually concentrate on sociocultural anthropology, archaeology, linguistics, or biophysical anthropology. Sociocultural anthropologists study the customs, cultures, and social lives of groups in settings that range from unindustrialized societies to modern urban centers. Linguistic anthropologists investigate the role of, and changes to, language over time in various cultures. Biophysical anthropologists research the evolution of the human body, look for the earliest evidences of human life, and analyze how culture and biology influence one another. Physical anthropologists examine human remains found at archaeological sites in order to understand population demographics and factors that affected these populations, such as nutrition and disease.

Archaeologists examine and recover material evidence, such as the ruins of buildings, tools, pottery, and other objects remaining from past human cultures in order to determine the chronology, history, customs, and living habits of earlier civilizations.

Geographers analyze distributions of physical and cultural phenomena on local, regional, continental, and global scales. Economic geographers study the distribution of resources and economic activities. Political geographers are concerned with the relationship of geography to political phenomena, whereas cultural geographers study the geography of cultural phenomena. Physical geographers examine variations in climate, vegetation, soil, and landforms and their implications for human activity. Urban and transportation geographers study cities and metropolitan areas, while regional geographers study the physical, economic, political, and cultural characteristics of regions ranging in size from a district to entire continents. Medical geographers investigate health care delivery systems, epidemiology and the effect of the environment on health. Most geographers use geographic information systems (GIS) technology to assist with their work.

Historians’ research, analyses, and interprets the past. They use many sources of additional information in their research, including government and institutional records, newspapers and other periodicals, photographs, interviews, films, and unpublished manuscripts such as personal diaries and letters. Historians usually specialize in a country or region, a particular period, or a particular field, such as social, intellectual, cultural, political, or diplomatic history. Historians help study and preserve archival materials, artifacts, and historic buildings and sites.

Working Conditions

Social scientists often work as an integral part of research team, among whose members good communication skills are important. Social scientists on foreign assignment must adjust to unfamiliar cultures, climates, and languages. Some social scientists do field work. Social scientists employed by colleges and universities usually have flexible work schedules, often dividing their time among teaching, research, writing, consulting, and administrative responsibilities.

Employment

Social Scientists work as researchers, administrators, and counselors for a wide range of employers. Other employers included scientific research and development services; management, scientific and technical consulting services; business, professional, labour, political, and similar organizations; and architectural, engineering, and related firms. Many individuals with training in a social science discipline teach in colleges and universities and in secondary and elementary schools.

Training

The educational attainment of social scientists is among the highest of all occupations. The Ph.D. or an equivalent degree is a minimum requirement for most positions in colleges and universities and is important for advancement to many top-level non academic research and administrative posts. Graduates with master’s degrees in applied specialties usually have better opportunities outside of colleges and universities. Graduates with a master's degree in a social science may qualify for teaching position. Bachelor’s degree holders have limited opportunities and, in most social science occupations, do not qualify for “professional” positions. The bachelor’s degree does, however, provide a suitable background for many different kinds of entry-level jobs, such as research assistant, administrative aide, or management or sales trainee. With the addition of sufficient education courses, social science graduates also can qualify for teaching positions in schools.

Training in statistics and mathematics is essential for many social scientists. Mathematical and quantitative research methods are being increasingly used in geography, political science, and other fields. The ability to utilize computers for research purposes is mandatory in most disciplines. Numerous museums, historical societies, government agencies, and other organization offer internship and research opportunities.

Depending on their jobs, social scientists may need a wide range of personal characteristics. Intellectual curiosity and creativity are fundamental personal traits, because social scientists constantly seek new information about people, things, and ideas. The ability to think logically and methodically is important to a political scientist comparing, for example, the merits of various forms of government. Objectivity, having an open mind, and systematic work habits are important in all kinds of social science research. Excellent written and oral communication skills also are necessary for all these professionals.
