CHAPTER I
INTRODUCTION


The world as a whole is now adjusting itself to the competitive realities of a new set of competitive standards. In the old economy competitive success was based almost exclusively on the ability to improve productivity .In the new economy, organization and nations compete in quality, variety, customization, timely response etc. So manufactures must be able to develop and produce customized products rapidly to meet ever changing customer needs to be ahead of others.

Methods to meet these requirements are the basics of agile engineering. Agile Engineering or Manufacturing is a new concept of management originating from USA aimed at carving a new path for business enterprises. The emphasis is to make the organization quick shift in style of working to adopt the changes in market environment in order to remain the business leader ahead of competitors. Thus the ability to use and exploit a fundamental resource-knowledge and imagination is the impetus behind agile organizations.

1.1 HOW DO WE GET TO WHERE WE ARE TODAY?

The industrial revolution led to mass production practices and the scientific definition of cost accounting system. That period represented seller s market, where demand was greater than capacity. Price was based on the cost of production and expected profit. The fixed of capital was amortized for a long period of time, but variable costs were high and needed to be managed. The solution was simple treat manufacturing as a cost driver by focusing on local optimization, breaking down to tasks into small simple steps and producing high volumes of standard products at the lowest possible cost. Consequently labor was de-skilled.


The computer revolution dramatically changed the market characteristic. Today it s the buyer s market where capacity is higher than demand. Price is dictated by the market and is not based on producer s expected profit. Manufactures must develop a balance between the external and internal measures. Their focus is changing to global optimization from local optimization by determining what customers want and delivering the right product.

Thus focus and advances in technology and product life which together with the high cost of capital makes product time to market are of the major business driven for many industries. This increasingly shorted whole resulted in the need for agility.

The Japanese who dominated the market at the middle of the 20th century had developed their own paradigm called LEAN MANUFACTURING .As the customers were shifting towards the Japanese the US introduced AGILE ENGINEERING IN 1991 so as to compete with them.


CHAPTER II
AGILE ENGINEERING-CONCEPT
AND PHILOSOPHY


Peter Drucker wrote There is only one valid definition of business purpose, to create a satisfied customer who determines what the business enterprise has two and only two basic functions: marketing and innovation.

Success globally means faster reach to market, sharper response to customer needs and exploiting the resources efficiently to develop the product. The emphasis is to make the organization quick, swift and agile in catching customer s requirements and to treat it to be very purpose of business. It requires a holistic business approach and reorganizing the organizational structure to make it cross functional and enabling.

2.1 HOLISTIC APPROACH

Winners do not do different things, but they do things differently
In order to achieve agility in a system it is necessary to break the fragmented organizational legacy and meaningful only in the context of the whole effort .It must be compatible on the company wide basis .An individual s effort to excel in his job or a single department doing its best within its domain is no more considered enough. Building up a holistic organization emphasizes not on parts but as whole. Each part of the organization must continuously adjust and recalibrate its actions to accommodate the needs and requirements of the whole. Holistic system of management can be thought of as the foundation of building agile organization to be capable of quickly responding to fast changes whether internal or external, simple or complex.

2.2 CROSS FUNCTIONAL MANAGEMENT

Communication gap across organizational boundaries was still remaining problem number one of the industry .It is mainly due to organizational legacy that divide a company into less and less co-operative parts. And in the absence of cross-boundary communication, management of complex process like new product development or increasing market share etc suffers or may require extraordinary efforts or resource .The solution to the problem is found out to be agile engineering by adopting cross-functional system of management

The agility of an organization depends on cross management communication. Company wide system reorganization was put into effect. Executives are assigned multiple and cross functional problems. This helps in sharing of ideas and concepts and hence enhancing company wide coordination.

The unique characteristics of cross-functional system can be summarized as below
1. Company wide cross department co-operation and communication
2. Focus on strategic core processes as a basis for achieving competitive results and profitability.

2.3 HIGH SENSITIVITY

Agile organizations should be sensitive enough to pick feeble signal of changes and be responsive enough to take corrective measures instantaneously. It should be in a state of continuous instability rather than being in a static equilibrium. This agility will come out of this vibrant and dynamic state which instead of causing a destabilizing effect on the system would provide ability to quickly perceive and adapt the market needs, technology, opportunities, new employee competencies, competitive threats or new regulations.


2.4 INTERNAL AND EXTERNAL AGILITY

Internal agility concerns itself with the ability to react quickly to changes in rapidly changing products, processes and the physical environment of the factory. External agility is something more and more companies are dealing with by focusing on their on competitors and forming partnerships with other suppliers to meet overall customer needs.

The commercial and legal risks are not widely understood and most of the interest in partnerships building has been based on forming long term commercial relationship.

CHAPTER II
AGILITY: A POPULAR PARADIGM
WITHIN MANUFACTURING


The paradigm of mass production has first shifted to lean manufacturing and now to Agile Engineering to respond rapidly to change in customer demand. This radical approach challenges some fundamental operational issues, producing high-volume item to cater for the larger segment of the market which also accommodates customers who went one-off, customized products without sacrificing on lead time and cost. A shift towards an agile enterprise will require manufacturing process to be well placed to exploit opportunities in a climate of uncertainty, unpredictability and highly turbulent market conditions.

Agile manufacturing rests upon three supporting pillars.

1. Learning in Agile organization.
2. Skilled people-Role of HRD.
3. Intelligent and flexible manufacturing technology.

3.1. LEARNING IN AGILE ORGANIZATIONS

Management is all about acts to achieve goals. Learning is the key to achieve these goals. Learning is a process which is inevitable to all the organizations either deliberately or without any focused effort.

3.1.1 ORGANISATIONAL LEARNING

The organizational learning can be termed as increasing capacity of an organization to take effective actions. Organizational learning is complex, as it is a large collection of diverse individuals.

Primary source of individual learning is through experimental learning is through experimental learning as shown below.






Fig 3(A)

The above cycle gets modified in the case of organizational learning as follows.

3.1.2 LINKAGE OF LEARNING WITH PERFORMANCE

Learning without thought is labor lost and thought without learning is perilous Knowledge by itself produces by itself produces nothing .It can become more productive only when it is integrated into a task. And that is why knowledge society of organization.

Learning curve is defined as empirical relationships between the numbers of units produced and the numbers of labor hours required to producing them. The average labor hours will come down as units produced goes up as shown below.
The only expertise these days fast changes is the expertise to garner expertise.


3.2 ROLE OF HUMAN RESOURCE DEVELOPMENT IN AGILE MANUFACTURING-A CASE STUDY

A mid-sized engineering consulting firm uses a web based optimization solution to give employees more options for self-service and increase the productivity of its human resource staff.

3.2.1 THE CHALLENGE

Agile Engineering a mid-sized consulting a mid size consulting firm faced a large backlog of opportunities for new projects but was struggling to build an adequate work force to handle the work load. From bringing new hires on broad, to keep company needed to enhance its workforce management tools and processes.

3.2.2 THE SOLUTION

Agile Engineering launched a work force optimization solution using the internet to advantage to give employees quick access to the information they needed to their jobs and to simplify and enhance a wide range of human resource activities. Employees themselves now can complete processes that are required a phone call or letter to human resources with a turn around of several days in minutes.

Fig .3(B)

3.2.3 THE STRATEGY AND BENEFITS

The work force optimization strategy for Agile centered on
Communications: Through a new company wide intranet, Agile Engineering gave employees a single, web based window into their company policies, directories etc.Making training available on line enabled employees to improve their skills at their convenience, without costly travel to the headquarters and without disrupting normal work schedules. This helped to respond more quickly to problems and opportunities.
Transaction related solutions: Agile s engineers work in three remote sites and frequently from their homes or customer sites. The workforce optimization solution eliminates the isolation of these remote employees by allowing them to use any web connection to update their benefits choices, report expenses and complete performance reviews at their convenience.
Strategic HR activities: The work force optimization solution provided human resources with new tools to finding and hiring skilled employees. Using internet agile was able to reach candidates all over the world.

3.2.4 RESULTS

1. Reduced Costs: Agile saw dramatic reductions calls to HR staff about routine matters. Online training services helped reduce travel and facilities cost. The firm also reduced paperwork and costly error in tasks such as expense reporting, benefits, adjustments and hiring.
2. Empowered Employees: Employees on the Agile network can take control of their careers and benefits information by receiving and manipulating their personal employment records on line, from the office or home.
3. Improved Productivity: With the flexibility to find the needed information in one place, available at anytime anywhere, Agile employees can focus on their core activities. For HR,workforce optimization solution reduce routine task and allow more time for finding, hiring and retaining the best possible employees. This scenario keeps the company competitive, reduces cost and increases profitability.

3.3 INTELLIGENT AND FLEXIBILE MANUFACTURING TECHNOLOGY AGILITY IN AUTOMOTIVE SYSTEMS

With the Indian automobile industry now open to global players, competition has set in and the customer has a wide choice now. The mechatronics application in automotives has revolutionized the automobile industries. Computers are the electronic devices that stores data, manipulate them through arithmetic and logical operations and an output according to the instructions already given to it.

3.3.1 FUNCTIONS OF MECHATRONICS IN AUTOMOBILES

A single microprocessor in an automobile may do the following
1. Carburetor/Fuel injection control
2. Spark timings
3. Idle speed of the engine
4. Cruise control
5. Air management
6. Exhaust control
7. Transmission control
8. Instrumental panel display
9. Self-diagnosis of the system
10. Passenger safety aspects.

The brain behind all these functions is a small digital computer which contains the logic for the entire system.



CHAPTER IV
AGILE AND LEAN MANUFACTURING
ADVANTAGES OF AGILE

4.1 COMPARISION

The two concepts are more or less same in certain areas.

PRINIPLES AGILE LEAN
Delivering values to customer High High
Being ready for change Yes Yes
Valuing human knowledge and skills High High
Forming virtual relationships Short and flexible Long and rigid
Table 1

4.2 ADVANTAGES OF AGILE ENGINEERING

1. The first is the change from standardization to post standardization .Industrial society was characterized by high volume production of small variety of items. An information society however is capable of small production runs of multiple items which match individual needs.
2. The second is the shift from specialization to collaboration, with many aspects of society becoming increasingly composite and multidisciplinary.
3. The third is the shift from constraints of time and place.
4. The fourth is the trend away from concentration and diversification.
5. From centralization to decentralization
6. Finally leading to sustainability in manufacturing

CHAPTER V
CONCLUSION


The new economy requires management technologies, work force that are flexible and roboust, agile engineering. The new markets standards would not have been possible without an equally new role for technology. Thus agile manufacturing techniques has fully exploited the flexible new technology, by using it in conjunction with equally flexible workforce and organizational formats, have raised the level of competition and increased the range of competitive standards.

Agile Manufacturing

The need for manufacturing agility in today s
economic climate

Expert Opinion by Andy Brown
In today s global market the challenges of managing high levels of demand are now
less prominent. Where efficiency, service and capacity utilisation have traditionally
been the main objectives, these have been replaced with other challenges which
could remain for the next 3 years or more.
On the demand side, there has been an increase in product complexity and
diversity driven by ever more discerning and selective customers. The demand,
however, is considerably less predictable as customers recognise that capacity is
no longer constrained and therefore look to trade off suppliers to gain the shortest
lead times at the lowest cost. In addition to this, there is a need to continually
improve value to the customer, whilst reacting to the ever-changing green agenda .
The impact of the recession on lending and general deflationary pressures make
finding business investment more challenging than ever before and as the global
economy moves out of recession, it will re-structure based on who can move out of
recession first this may fundamentally change manufacturers customer base and
the markets they serve.
On the supply side, manufacturers have to face up to managing increased spare
capacity and make tough choices on how and where they make products and fulfil
demand. To achieve this, manufacturers will have to: respond quickly and frequently
to changes in product mix; maintain optimal inventory levels; and maximise both
production process capacity and raw material utilisation.
Manufacturers will also need to build the capability to accurately and efficiently
communicate requirements to suppliers, ensuring they can respond to plans and
identify potential vulnerabilities.
In all these challenges manufacturers must be agile to support the market s demand
for sustainable products and supply chains.
Is Agile Manufacturing the
next step after Lean?

Firstly, it s probably worth covering some fundamentals.
Organisations that employ lean manufacturing
techniques drive efficiencies out of the activities they
are in control of, whereas organisations that use agile
techniques are better at managing activities, or reacting
to the circumstances they are not in control of. Wikipedia
explains the difference between lean and agile as being
the same as the difference between thin and athletic.
For many, lean manufacturing is seen as a set of
techniques and tools to identify and eliminate waste,
thus improving quality and reducing cost it is therefore
well suited to relatively stable markets where cost is
the main concern of the customer. Agile, however,
is more focused on responding rapidly to customer
demands and market trends, and is therefore suited
to fast-changing markets and especially some CPG
sub-sectors like fashion, food and hi-tech.
In reality though, organisations can benefit from both
lean and agile approaches to manufacturing and
supply chain management a balance of lean and
agile approaches is referred to a leagile.
So what elements form the core of an agile
manufacturing model?
Lean product innovation efficiently developed
products and short time to market in order to
maximise growth and profitability
Planning manufacturing strategy is aligned with
overall business strategy. Demand and supply
planning balances business needs with constrained
supply resources. Manufacturing planning ensures
most effective use of manufacturing assets to meet
short-term customer demand
Supply chain re-engineering the global supply
network is re-engineered to ensure the highest
levels of customer service at minimum cost
Leagile production development and
management of efficient and flexible factories where
waste is eliminated
Design to manufacture highly developed
integrated processes that support rapid response
to changes in supply and demand types, short lead
times, and flexible service.

Agile Manufacturing is a term applied to an organisation that has created processes, tools and training so that it can respond quickly to the needs of customers and changes in the market while continuing to control costs and quality.An enabling factor for becoming an agile manufacturer has been the development of manufacturing support technology that enables marketers, designers and production staff to share a common parts and product database, share data on production capabilities and problems. Problems can have major downward effects. It is a general proposition of manufacture that the cost of correcting quality problems increases as the problem moves down, so it is cheaper to correct quality problems at the earliest possible point in the process.

Agile manufacturing is considered as the next step after light manufacturing in the evolution of production methodology. The dominant difference between the two is as between a slim and athletic, agile person who is the last. One can be none, one or both. In the theory of fabrication, being is often referred to as a leagile. According to Martin Christopher, when companies have to decide what to do, they have to look at the Customer Order Cycle (COC) (the time customers are willing to wait) and the delivery time to get supplies. If the supplier has a short lead time, reduced production is possible. If the COC is short, agile production is beneficial.Agile Manufacturing is an approach to manufacturing that focuses on satisfying the needs of customers while maintaining high quality standards and controlling the total costs involved in the production of a particular product. This approach is aimed at companies working in a highly competitive environment where small variations in performance and product delivery can make a big difference in the long run to a company's survival and reputation among consumers.

This concept is closely related to lean manufacturing, where the goal is to reduce waste as much as possible. In lean manufacturing, the company aims to reduce all costs that are not directly related to the production of a product for the consumer. Agile manufacturing may include this concept, but it also adds an additional dimension, the idea that customer demands need to be met quickly and efficiently. In situations where companies integrate both approaches, they are sometimes said to use "lean and lean manufacturing". Companies that use an agile approach to manufacturing tend to have very strong networks with suppliers and related companies along with numerous cooperative teams working in the industry. Company to deliver the products effectively. They can recondition facilities quickly, negotiate new deals with suppliers and other partners in response to changing market forces, and take other steps to meet customer demands. This means that the company can increase product production with high consumer demand as well as redesign products to respond to problems that have emerged in the open market.

Markets can change very quickly, especially in the global economy. A company that can not adapt quickly to change can fall behind, and once a company starts to lose market share, it can fall quickly. The goal of agile manufacturing is to keep a company ahead of the competition for consumers to think about that company first, allowing it to continue innovating and introducing new products because it is financially stable and has a strong customer support base .
Companies that want to switch to using agile manufacturing can benefit from consultants who specialise in helping companies convert and improve existing systems. Consultants can offer tailor-made advice and assistance to the industry in which a company is involved, and generally focus on making companies competitive as quickly as possible with proven agile techniques. There are also a number of textbooks and manuals available with additional information on agile manufacturing techniques and approaches.
