3. 1. PRODUCT DEVELOPMENT
Product development typically refers to all stages involved in bringing a product
from concept or idea through market release and beyond. In other words, product
development incorporates a product's entire journey.
Definition: Product development refers to the creation of a new product which has
some utility; or up-gradation of the existing product; or enhancement of the
production process, method or system. In simple words, it is all about bringing a
change in the present goods or services or the mode of production.

4. Stages of Product Development
Stages of Product Development includes process of
generating, selecting, developing, and commercializing
product ideas.
a) Idea Generation: The first step in the new-product
development process is to come up with some ideas that
will satisfy unmet (ಸಾಧಿಸದ) needs. Customers, competitors,
and employees are the best source of new product ideas.
b) Idea Screening : From all the ideas under consideration,
the company selects those that appear to be worthy of
further development, applying criteria such as whether the
product can use existing production facilities and how
much technical and marketing risk is involved.

5. Stages of Product Development
c) Business Analysis: A product idea that survives the screening stage is subjected to a business
analysis. During this stage, the company reviews the sales, costs, and profit forecasts to
determine whether they meet the company's objectives. If the product meets the company's
objectives, it can then move to the prototype development.
d) Prototype Development: At this stage, the company may actually develop a product concept
into a functioning product. For physical goods, the firm creates and tests a few prototypes, of the
product, including its packaging. These units are rigorously analyzed for usability, durability,
manufacturability, customer appeal, depending on the type of product. Prototypes used for
testing and evaluation.

6. Stages of Product Development
e) Marketing Strategy: Once a company decides on the product, they will have to spend time
developing a marketing strategy for it. Experts will evaluate the size of the market, demand for the
product, and revenue estimates. The marketing team will get a budget for their efforts and they can
select distribution channels.
f) Business Model: The development of a business model works very similarly to the development
of a marketing strategy. The experts in the company will estimate the costs and profits of the
product. Also, they will estimate the economic feasibility of the new product.
g) Manufacture: At this stage, the production finally begins. The company will make multiple
prototypes and choose on which designs get to go to the next stage. Also, the company will, once
again, perform a cost analysis to see if it matches the estimates or not.

7. Stages of Product Development
h) Branding and Product Launch: Once the company
finally has a physical product in their hands, the
marketing team can get to work. For starters, they can
develop the brand name, packaging, and the marketing
message behind the product. They will also determine
the price of the product.
g) Commercialization The final phase of the product
development process is the commercialization phase.
The product is launched, and it is followed by a developed
marketing strategy in order to maximize its earning
potential.

Need for Product Development
a) Meeting Changes in Consumer Demand: Change is a universal phenomenon in today's time
of science and technology. For example, a quick change in the food habits, comfort
preferences, tastes, customs and traditions, needs and expectations, etc.
b) Making New Profits: In Product Development and Manufacturing it has becomes quite
necessary for the organizations to come up with the new and innovative products that can
replace the old product which is on the verge of declining.
c) Handling the Environmental Threats: There are various environmental threats, these
threats spring from various environmental factors, like socio- economic, technological,
political, and demand and supply, etc. Moreover, the biggest threat that is always present in
such environment is competition in the market and products.

9. 9
d) Other Necessities: The other strategic needs for product development are as
follows:
• New products can provide the organization a source for gaining competitive
edge.
• They can ensure long-term financial return on the investments made. They
also help in optimum utilization of the available resources.
• New products make best use of research and development.
• They can provide new opportunities for making changes in the strategic plans
of the company.
• New products can bring most out of the marketing practices and brand equity.
• It enhances the corporate image of the organization/brand.

10. Product Development Feasibility study
10
A new product feasibility study is a market research methodology that aims to
provide predictive analytics to guide the next steps for marketing, sales, and
product development.
The objectives of this type of market research often include obtain insight on:
• Product placement
• The target market
• Marketing and advertising.
• The competition
• Pricing strategies

11. 11
There may also be several secondary objectives included in the study depending
on your company's needs and specifications.
For a product feasibility study Company conducts these type of market
research.
a) Demographic analysis
b) Competitive assessments
c) Pricing analysis
d) Online surveys
e) Stakeholder interviews

Development of design-Selection of Materials and Process
A Design Development is the design and engineering work process that is
based on basic Engineering information to develop the Detailed Design and
Engineering document for the procurement, construction, operation, and maintenance
of a project.
The Design Development defines and describes all important aspects of the
project focusing on the selection of materials; development of technical
specifications for detailed engineering and construction and generation of
construction drawings and document. During Design Development, design issues
should be resolved to fix the size and character of the entire project including civil and
structural, mechanical, and piping, control and electrical systems, and materials as
well as other operability and maintainability requirement.

13. 13
Development of design-Selection of Materials and Process
For a better Selection of Materials there are 5 steps
a) Bill of Materials [to know number of materials required, availability etc.]
b) Analysis of Performance, aesthetics and cost of production
c) Analysis of Prototype models using different materials and manufacturing techniques.
d) Evaluating the results and find the materials that satisfy the product-production needs.
e) Identification and selection of best results and update results to bill of materials
Materials selection is an ordered process by which engineers can systematically and rapidly
eliminate unsuitable materials and identify the one or a small number of materials which are
the most suitable. The approaches adopted for materials selection are by far the most
developed for this design discipline. There are many systematic methods, most numerically
based, with some implemented as computer software tools, for matching material properties
with technical design requirements.

14. 14
Manufacturing process selection is to establish selection criteria based on key
process selection drivers: manufacturing volumes, value of the product, part geometry,
required tolerances, and required material. The material choice will be very effective in
reducing your options down. This is because many processes work exclusively with certain
materials. For example, injection moulding can only be used with polymers, Die casting can
only be used with metals. Your material choice will instantly rule out a vast number of
unsuitable processes. The expected manufacturing volume will further narrow down your
process options. For a large quantity, a manual production process like manual machining
would be completely impractical. Instead, you would need to consider an automated
process such as moulding. The geometry and tolerances required for a product will also
filter out many processes that would be unable to achieve the desired accuracy.

Prototype-launching
Prototype "It is a simulation or sample version of a final product, which
manufacturing teams use for testing before launch." The goal of a prototype is to
test and validate ideas before sharing them with stakeholders and eventually
passing the final designs to engineering teams for the development process.
Prototypes are a crucial part of the design process and a practice used in all
design disciplines. From architects, engineers, industrial designers and even
service designers, they make their prototypes to test their designs before
investing in their mass production. The purpose of a prototype is to have a
physical model of the solutions to the problems already defined and cussed by the
designers during the concept/idea stage.

16. 16
Instead of going through the entire design cycle based on a imaginary solution,
prototypes allow designers to validate their concepts by putting an early
version of the vas solution in front of real users and collecting feedback as
quickly as possible. When Prototypes test fail it shows designers where the
defects are and sends them back to the design process”, to refine or repeat
the proposed solutions. In prototype test we can understand early fails;
prototypes can save lives, avoiding the waste of energy, time and money in
implementing weak or inappropriate solutions. Another advantage of
prototyping is that, because the investment is small, the risk is low

17. 17
Product launch
A Product launch is a planned effort to bring a new product to market. The
goal is to make sure that everyone inside the company, your partners and target
customers know about your new product. If you don't do the product launch
effectively, customers won't be aware of your solution, or may potentially have a
bad impression of your product, and you may not achieve your revenue and
profitability goals.
A product launch serves many purposes for an organization giving
customers the chance to buy the new product. It also helps an organization build
anticipation for the product, gather valuable feedback from early users, and
create valuable momentum and industry recognition for the company.

18. 18
A Product life cycle is the length of time from a
product first being introduced to consumers until it is
removed from the market. A product's life cycle is
usually broken down into four stages; introduction,
growth, maturity, and decline.
Product life cycles are used by management and
marketing professionals to help determine advertising
schedules, price points, and expansion to new product
schedules, price points, and expansion to new product
markets, packaging redesigns, and more. These
strategic on to new product markets methods of
supporting a product are known as product life cycle
management. They can also help determine when newer
products are ready to push older ones from the market.
