Variant Design
This type of design demands considerable scientific training and design ability, in order to modify the existing designs into a new idea, by adopting a new material or a different method of manufacture. In this case, though the designer starts from the existing designs, the final product may be entirely different from the original product.
E.g. converting mechanical watches into quartz watches. Here a new technology is adopted.

Adaptive Design
In most design situations the designer's job is to make a slight modification of the existing design. These are called adaptive designs . This type of design needs no special knowledge or skill. E.g. converting mechanical watches into a new shape.


Original Design
Here the designer designs something that did not exist previously. Thus, it is also called new design or innovative design. For making original designs, a lot of research work, knowledge and creativity are essential. A company thinks of new design when there is a new technology available or when there is enough market push. Since this type of design demands maximum creativity from the part of the designer, these are also called creative designs.

Selection Design.
It involves choosing one or more items from a list of similar items. We do this by using catalogues.
Eg. -Selection of a bearing from a bearing catalogue
-Selection of a fan for cooling equipment
-Selecting a shaft.

• Configuration / Layout / Packaging Design

In this type of problem, all the components have been designed and the problem is how to assemble them into the completed product. This type of design is similar to arranging furniture in a living room.
Consider the packing of electronic components in a laptop computer. A laptop computer has a keyboard, power supply, a main circuit board, a hard disk drive, a floppy disk drive and room for two extension boards. Each component is of known design and has certain constraints on its position. For example, the extension slots must be adjacent to the main circuit board and the keyboard must be in front of the machine.

Product Planning
Planning is the process used to develop a scheme for scheduling and committing the resources of time, money and people. A plan shows how a project will be initiated, organized, co-coordinated and monitored. A product plan is a decision-making as regards to the design and manufacture of a product, by considering the revenues from different products. For example assume that a company already manufacturing 3 products, say P 1 , P 2 and P 3 identifies a need to design a new product ‘N'. Owing to the design and manufacture of the new product, the production volume, and hence revenue from products P 1 , P 2 ,and P 3 may be affected (due to re-allocation of company resources such as raw materials, machineries). In this situation, the company has to decide a time-schedule for the design and manufacture of the new product. Such plan made by the management is called the product plan. It must contain the time-as well as resource allocation for each of the products. More over it will result in optimum and efficient use of resources. After the product plan in made, the management begins a project for a new product design.

Organisational Structure of Design Teams
Since a design project requires individuals with different fields of expertise, they can be organised into different structures. Listed below are the five organisational structures. The number in the bracket shows the percentage of design projects that use that particular organisation structure.
1. Project matrix, (28%)
It is an organisation structure having the features of project and matrix organisations.
2. Functional matrix (26%)
It is another organisational structure obtained by combining functional as well as matrix organisations.
3. Balanced Matrix (16%)
Here the project manager and functional manager work together. A project manager is assigned to oversee the project, and the responsibility and authority for completing the project rests with functional managers.
4. Project Team (16%)
A project manager is put in charge of a project team composed of a core group of personnels from several functional areas or groups assigned on a full time basis.
5. Functional Organisation (13%)
Each project is assigned to a relevant functional area or group within a functional area. A functional area focuses on a single discipline.

Hierarchy of Human needs:-
Maslow developed a hierarchy of human needs as given below
1. Physiological needs
- These are the basic needs of the body- For example, thirst, hunger, sex, sleep etc.
2. Safety and security needs
For a person whose physiological needs are met, the new emerging needs are safety needs. These include, protection against danger, threat etc.
3. Social needs
Once the physiological and safety needs are met, the next dominant need is social need. For example he/she want to Study and be loved, he want to be “in group”, etc.
4. Psychological needs
These are the needs for self-respect and self- esteem, and for recognition.
5. Self-fulfillment needs
These are the needs for the realisation of one's full potential through self-development, creativity, and self-expression.
