Brief

• A lot of talk recently occurred about value engineering, its applications, and the success of the global and local levels that applied in.

• Value engineering is not specialized engineered - as is the case in science Computer Engineering or Electrical Engineering or Civil, but is a method and a structured methodology to solve problems, whether administrative or engineering, or manufacturing.

• The approach value engineering of the most important and most programs that have been implemented.

• Now in much of the country technologically advanced method has value engineering is a scientific method thoughtful became with effectively by a lot of companies and institutions global engineering and local communities.

• And their success is due to it easier for product decision-making and help them to get the greatest return material at the same time achieving the goals and tasks required, taking into account access to jobs desired by the product, such as Beauty and the environment, safety and flexibility and other important factors that meet or exceed the expectations of the product and the customer.

• Where this method in the development of performance and productivity on the idea of

combining to achieve targeted production, whether through the construction of projects or the provision of goods and services, and achieve cost savings without compromising quality and basic functionality expected by customers and producers.

Value Engineering

Introduction

Introduction

• Value Management concentrates on the actual needs of the user to focus its resources. It is different to cost-cutting exercises, which achieve economies by using less or cheaper materials.

• The Value Management approach involves the use of creative techniques, combined with the latest technical information on materials and construction methods.


Introduction

• Value, in its broadest sense, is the benefit to the client offered by a project. Value means ensuring that the right choices are made about obtaining maximum benefit for the client within time, cost and quality constraints.

• Value Management is a process that gives all stakeholders in a proposed development the opportunity to be involved in the decision-making process. It constitutes an examination of all relevant options for the design and construction of the project, leading to a refinement of the design brief and identification of any budget constraints.

• Value Management is a structured, systematic and analytical methodology that seeks to achieve the essential functions of a project at the lowest total cost, consistent with required levels of performance and quality.

• The underlying assumption to Value Management is that there are always many ways to achieve any function, and that an examination of alternatives may produce a better-value solution.

What is

Value Engineering?

What is Value Engineering?

• Value Management originated in the United States emerging resulted from components and materials shortage in the manufacturing sector during World War Two. Mr. Lawrence Miles (The Founder of Value Management, then known as Value Analysis) of The General Electric Company was greatly responsible for the establishment of the technique in 1942 and since then the technique is very much accepted in various industries.

• Presently United States Government and many other nations such as United Kingdom, Japan, Korea, Australia, Saudi Arabia amongst others adopt Value Management technique to be applied for their Capital work projects.

• If, for example, the buyer wants to get more item value, he/she needs to either increase the item's functionality at the same time he/she is containing cost; or he/she needs to reduce cost while holding or improving its functionality. Either way, the result is more value for the customer .



• Value Engineering (VE) Is an intensive, interdisciplinary problem solving activity that focuses on improving the value of the functions that are required to accomplish the goal, or objective of any product, process, service, or organization.

• VALUE METHODOLOGY “The systematic application of recognized techniques which identify the functions of the product or service, establish the worth of those functions, and provide the necessary functions to meet the required performance at the lowest overall cost.”

FUNCTION + Quality

VALUE = ـــــــــــــــــــ

Cost



Bone and Law (2000) identified ten mandatory characteristics of Value Management practice:

1. It is visibly supported by senior management.

2. It generates a clear program of work.

3. It involves structured team-based workshops.

4. It employs a range of analytical tools.

5. It involves creative brainstorming.

6. It is led by a qualified value practitioner.

7. It follows a structured ‘Job Plan’.

8. It involves customers.

9. It involves suppliers.

10. It causes study terms to achieve sustained improvements.



According to Dell I’sola, the relationship between Value, Function (Worth), Quality and Cost can be symbolized as follows:-

FUNCTION + Quality

VALUE = ـــــــــــــــــــ

Cost

Where:

• Function = The specific worth that a design/item must perform

• Quality = The owner’s or user’s needs, desires, and expectations

• Cost = The life cycle cost of the product/project.

• Value = The most cost effective way to reliably accomplish a function that will meet the

user needs, desires and expectations.

• Value Management studies can take place at any stage in the development of a project. However it is acknowledged that there is the potential for greater return on investment if it is used at the very clear stages illustrated in figure 3 and 4 below.

• As such Value Management should be performed as early as possible even before the commitment of funds, approval of systems or design as to maximize results.

Why & When to Apply Value Engineering ?


When to Apply Value Engineering ?

o The cost of making changes and remedial works will be greatly increased later in the development stage.

4-Evaluation

Phase

• Plan how to sell ideas to management, identify key recommendations, plan management presentation.

5-Development Phase

• Give oral presentation to management, or develop written report.

6-Reporting Phase


Six Steps VE Plan

1. Information Phase

What do you need to know about the problem that you don’t know now?

o What facts are known?

o What are the requirements of the system?

o Are these facts, opinions, assumptions, or

prejudices?

Where or how can information be obtained?

3. Creativity Phase

Creativity is the art of bringing something new into existence. It has the art of making, inventing, or producing something new and different.

“ You must blast before you can create. Blow apart the misconceptions, skeptics, and naysayers. Blow-up the preconceived ideas and common theories of how things should be done. Rather, focus on possibilities.”

J. R. Wixson -2004

“ Imagination is more important than knowledge, for knowledge is limited, while imagination embraces the entire world.”

Albert Einstein

IDEAS Vs. Solutions

o A solution requires justification & validation, and idea needs no justification.

o A solution is an end point, an idea is just the beginning.

o A solution is solid and self supporting, an idea is tender and must be built upon.

DON’T KILL IDEAS WITH ROADBLOCKS !!
