INTRODUCTION TO VEA SYSTEMATIC APPROACH – THE JOB PLAN
VEA is a discipline which uses an organised creative approach to achieve an understanding of the function, values, and worth of products, processes, services and systems. It is a body of procedures and techniques which can be applied by every individual on a day-to-day basis as part of his/her job, or it may be applied by a multi-disciple group (team) of 3 or more members as a task force or in a workshop setting or as a project
VEA process is about change. It is a process which includes a series of distinct interrelated methods or techniques for achieving value improvements and maximising the effectiveness of engineering, manufacturing, servicing and programmes to identify and solve problems.
The objectives of VEA are to identify problematic area such as high lead time; high rejects or reworks; high costs; high labour costs, high scrap rate; too much paperwork; etc; and to create alternatives which have the optimum combination of value characteristics. This process is not a replacement for decisions that are normally made, but a step-by-step procedural tool that permits the consideration, weighing, and documentation of all important factors leading to a given decision. It is a process that permits justification of a chosen approach. In order that consistent decisions can be made and documented, the process is disciplined and formalised. It is therefore a proven management technique.
VEA is not the followings
Design Review
Just correcting omissions made in design drawings and calculations
Cost Reduction Programme
Just cutting down costs by sacrificing needed quality, reliability and performance.
Value Engineering SG OMTI2014 V1CM
Page 33 Copyright © PSB Academy
Quality Audit
Just review fail-safe reliability status and of inspection/test procedures and methods.
Method Study or QC
Just improvement of method, procedure, productivity, quality and services.
VEA is more than all the above. It helps to identify functions, to quantify worth and costs, to analyse competitors’ information, to create alternatives and to evaluate them to develop and innovate a breakthrough.

INFORMATION PHASE – FUNCTIONAL AND COSTS ANALYSIS
This phase has two parts: Information Gathering and Functions and Costs Examining. The goal of this phase is to identify areas of the project that are high in cost and low in functional worth. Another goal is to develop a common understanding of the project among the team members. This goal is accomplished by using a set of questioning techniques of which one of them is the 5 W 1 H Method (or the 5 W 3 H):
Purpose What?
Reasons Why?
Person Who?
Place Where?
Sequence When?
Mean How to do?
----------------------------------------
Quantity How many?
Costs How much?

Part I – Information Gathering
The purpose of information collection is to gain as much information and knowledge as possible on the existing design in order to enhance the level of thinking at each phase of VEA. The process of information gathering shall not be stopped at this information phase and shall be continued to seek information if the phase requires additional information.
The following points to be considered for:
Clarify what the necessary information is required by having definite purpose.
Know the scope of information collection as well as the quality and quantity of information.
Find out the right sources for information collection – publications; contractors; competitors; libraries; experts; consultants; manuals; brochures; catalogues; drawings; exhibitions; symposiums; factory visits; supervisors; workers; etc.
Study the right methods of collecting information – surveys; feedback; interviews; focus group discussions; field tests; meeting; questioning techniques; etc.
Ability to separate actual facts from opinions or surmise.
Ability to choose the right timings for the collection of information and to adjust the length of the period for information collection.
Do not assume things – make it a point that you do not know.

Part II – Function and Cost Analysis
The purpose of this part are important to:
Clearly define the work involved and the requirements for the project.
Separate those non-essential areas of the project that are being provided for support more than to perform by specified requirements.
Identify both basic and secondary functions required for the project.
Identify the cost and the work related to the project.
Analyse the functions and costs by questioning techniques.
The key general questions to be considered are
What is it for?
What are the functions?
What is the basic function?
What must it do?
What are the necessary support functions?
What must be supporting its main or basic function?
What does it cost?
Value Engineering SG OMTI2014 V1CM
Page 39 Copyright © PSB Academy
What is it worth?
Why is it necessary to have such function
What is the purpose of each part?
Can we climinate the part?
Can we combine the part with other part?
The Function and Cost Analysis and its techniques will be discussed in greater depth in Session 3 and 4. From this analysis approach, we can see several advantages:
It forces conciseness and eliminates fog;
It identifies what the buyers wants in term of functions, not things;
It distinguishes between the parts and the functional approach;
It forces us to think in greater depth;
It helps us to communicate what we are actually doing into a more enthusiastic give and take discussion of cost versus worth and function, and
It forces us to question the design in terms of quality, functions, costs and times
Value Engineering SG OMTI2014 V1CM

SPECULATION PHASE – PROBLEM IDENTIFICATION AND CREATIVITY TEHNIQUES
This is the creative phase of the Job Plan. Here the team’s goal is to generate as many alternative ideas as possible for accomplishing an identified basic function of the project. During this phase all critical judgement of the alternative ideas is withheld. Switching to the fun child ego state during the free-wheeling speculation phase, as many ideas as possible are recorded.
The key general questions to be considered are:
1. What else will do the job?
2. How will it work in other ways?
3. Can we find another ideas by combining ideas?
4. Can we find another ideas by reversing this idea?
5. How can its value improve by adding support functions?
6. Can we eliminate some functions to improved value?
Creativity is the thinking process that requires both the left and right brains to help us to generate ideas. It is an organised systematic idea generating process where many techniques have been developed to assist the team to achieve better ideas.
Value Engineering SG OMTI2014 V1CM
Page 41 Copyright © PSB Academy
Innovation, on the other hand is the second part of the speculation phase where the team can generate ideas that will work. Ideas, which may be too imaginative or too impractical, shall be eliminated. And ideas, that will work, will be analysed, evaluated and developed into the best solutions later. Innovation can lead to a breakthrough, i.e., a complete new product or process or system which is completely different from
CREATIVITY PROCESS INNOVATION (idea) (breakthrough)
Refer to Session 5 for Creativity Techniques.
EVALUATION AND DEVELOPMENT PHASE-SELECTION OF BEST ALTERNATIVE
The purpose of this phase is to compare and analyse the different alternative idea among those generated during the speculation phase, and to evaluate and select the best workable ideas for further development. It is during this phase when we start to criticise the advantages and disadvantages of them and group them into our business objectives as well as our project objectives shall be evaluated by ranking or point system selection techniques to select the best ideas for development.
The key general questions to be considered are:
1. Will each idea perform the required function?
2. What does each cost?
3. What would each save?
4. Will each perform the basic functions better than the others?
Value Engineering SG OMTI2014 V1CM
Page 42 Copyright © PSB Academy
5. Will each idea be safer, be lighter in weight or look better?
6. Will each idea meet the customer requirements?
7. Will each idea better than the competitors?
8. Will each idea reduce the number of parts per unit?
9. Will each idea employees No. of processes?
If the answers of some of the above questions are “no”, always ask the follow-up question, “Why not?” This will give you a list of objections that you should deal with one at a time by asking “How can we overcome that objection?” Modify each idea minimally – only enough to overcome the latest objection.
Each idea is evaluated against the others in sufficient details using the appropriate evaluation techniques to determine whether it could achieve better value if it will be able to work or make to work. The alternative ideas that have survived the analysis and evaluation phase are developed into firm specific and practical designs. Each idea is subjected to experiments, testing, costing, and trial runs to prove its values.
PRESENTATION PHASE – ORAL AND WRITTEN PRESENTATION TO MANAGEMENT
The presentation phase involves the actual preparation and presentation of the best alternatives to persons having the authority to approve your proposals. This is accomplished in two ways, i.e. an oral presentation and a written report.
Value Engineering SG OMTI2014 V1CM
Page 43 Copyright © PSB Academy
An Oral Presentation
An oral presentation is designed to preview your written proposal. It is a good practice to submit the written report to the management personnel who will be the audience of your oral presentation two weeks before the oral presentation. This is to ensure that they can understand the project and can raise the right questions to you at the oral presentation. Your oral presentation will be more effective and easier to prepare if you follow the following format structure:
Introduction
Objectives
Data Collection and Analysis
Evaluation and Comments
Recommendations and Results
Budget and Approval
During the oral presentation, the following guidelines should be considered:
Make it a formal presentation to seek approval for implementation.
Make it a point to follow the above format structure of your written proposal report.
Let the audience know why they should listen.
Know your audience background and their wishes.
Get feedback from the audience at each planned intervals of times.
Use eye contact with the audience to gauge their attentiveness and responsiveness.
Value Engineering SG OMTI2014 V1CM
Page 44 Copyright © PSB Academy
Apply body gestures meaningfully.
Speak at a volume so that all can hear.
Ensure visual aids are clear, relevant, short and sharp.
You should dominate the scene not the visual aids.
Present the savings, benefits and simplicity of the proposals, as against the disadvantages, limitations, wastes and complexity of the present design.
Ask for the “ORDER” – request a decision from management personnel.
A Written Report
It documents your team’s efforts and provides a detailed plan of action for each alternative. The first step is preparation. You should identify your readers and approvers of the project and decide what are the main purposes for the project. Then you should plan the contents of the whole report.
There are two approaches to write a VEA report:

IMPLEMENTATION AND FOLLOW-UP PHASE – INSTALLATION AND MAINTENANCE OF THE BEST DESIGN
The purpose of this phase is to develop an implementation plan and use it to monitor the status of the progress. The implementation plan designates responsibilities to take charge of the activities and makes visible the proposed schedule and the set of tasks required to accomplish the proposals. During the reviewing and monitoring, the results and savings are recorded and published, ensuring everything is on track.
The key general questions to be considered are:
1. What are the implementation activities or steps?
2. Who is responsible for each activity?
3. Who is the project manager?
4. What is the status of progress?
5. Can we have more savings and better results?
6. Is everything on schedule?
7. Any alternate plan if the original plan is our of control?
8. Is the budget for implementation approved?
During the Follow-up phase, parts of the proposals or new design may have to be changed.
Value Engineering SG OMTI2014 V1CM
Page 52 Copyright © PSB Academy
The importance of the Follow-up phase is best put in the book “In Search of Excellence”.
“The scarce people are the ones who have the know-how, energy, daring and staying power to implement ideas”. Since business is a “get thing done” institution, creativity without action-oriented follow through is a barren form of behaviour. In a sense it is irresponsible”.
During this phase, the following guidelines should be considered:
1. Construct a good implementation schedule plan stating the activities in sequence, the person in-charge of each stages and the time frame required.
2. Conduct regular reviews to keep all concerned informed of the progress and need of their supports. Report to management on the status of progress of implementation.
3. Continue “Protected Times” i.e., meeting on regular intervals with team to review progress and to determine follow-up actions required.
4. Allow people to fail with dignity.
5. Always recognise and reward successes.

Abstract
The purpose of this project is to effect Improvement and Cost reduction on the functions and components of “Bostitch” stapler without compromising its quality and reliability.
The experiment examines the functions of a bostitch Stapler as well as Cost Improvement through developing new alternatives using the value analysis techniques.
Four alternatives are proposed and they are:
Removing the existing staple remover by incorporating it to the lower body of the stapler.
Value Engineering SG OMTI2014 V1CM
Page 56 Copyright © PSB Academy
Improve the staple pusher for easy loading by forming a thumb grip on the top surface of the pusher guide.
Changed the plastic base catch method of fastening into the slotting method to eliminate wear on the plastic catch and better fitting of the base to the lower body to the stapler.
Incorporating a plastic casing at the bottom of the base to act as staple container. This will prevent cracking of the base when it was dropped onto the floor and to reduce the effort of searching for staples when the user may have forgotten to bring along a box of stapler to another place.
Our group had spent a total of 10 meeting session indulging in this project and one thing for sure, we had learnt to discipline ourselves in understanding the concept of value engineering.
Background
Stapler has been part and parcel of our daily needs whether you are at home or at work as it comes in handy when you have piles of documents to file.
“Bostitch” spring crown stapler is grouped under medium duty stapler. Due to its extra driving power, it is more suitable for compiling thick documents and for stapling the flaps of the carton during packing. As a result it is normally used in office and production areas.
The added advantage over the light duty stapler is the additional force to push the staple into a thick cardboard where light duty staple will crumble.
Although with its additional features such as locking system and stability provided by the plastic base, there are lots of feedback on its deficiency by the users. This prompt us to look into the necessary areas for improvement on the stapler.
Value Engineering SG OMTI2014 V1CM
Page 57 Copyright © PSB Academy
Objectives
The objectives of this value analysis project are:
To improve the function performance of the stapler.
To analyse the user’s feedback and put up a solution to satisfy their requirements.
To effect a cost reduction on the components through detail investigation of its function through value analysis techniques.
To ensure all improvements made do not have any prejudices to its quality and reliability.
Data/Facts Collection
Most data presented came from estimation by experience. The facts collected from the users are from the interview done on the clerks, secretaries, engineers, production analysis and supervisors.
Majority of the decisions made on the improvements came from the group’s consensus.

SPECULATION PHASE
After compiling all the relevant facts and data, each functions and facts are critically examined to determine its root cause as depicted below.
Root Cause
Plastic base catch
The catch is made of thermoset-plastic material and is used to clip the plastic base to the metal parts. Due to its weak resistance against the metal parts after a period of use, the catch wears off. This resulted in loose base and came off easily when handle it roughly.
Staple remover
Remover is placed in an awkward position and is obstructing the user’s fingers while holding it on the palm. It is attached to the stapler by the plastic catch and became loose when the catch wears off. This made the remover to dig into the staple in order to remove it and resulted in tearing the paper. Moreover, it made the staple look bulky.
Staple pusher
The pusher is chromed and provide a corrosion-free and smooth surface. Due to the strong force of the spring, the user has tendency to loose its group during the refilling of staple. This made the user to use its finger nails to push the pusher backward causing a painful experience.
Value Engineering SG OMTI2014 V1CM
Page 67 Copyright © PSB Academy
Development Stage
A brainstorming session is conducted to develop as many ideas as possible. During this time, no killing of ideas put fore is allowed and a total of 15 ideas were developed during this 3
rd sessions of meeting.
All alternatives are sorted out and only 9 alternatives are critically examined as show below.
What else will do?
Alternatives Advantages Disadvantages
1. Remove plastic base. 2. Incorporate the remover to the lower body. (refer to Figure 6)
3. Design an attachment for
light duty performance. 4. Form the thumb grip on the top surface of the pusher. (refer to Figure 7)
5. Change all metal parts to plastics.
Reduce cost Reduce cost Reduce weight No obstruction to finger when hold it. More rigid as no attachment required. Can be use for light duty staple. Additional function. Better grip. Reduce pain on the thumb for frequent use. Better performance and reduce frustration during loading. Reduce cost
Stapler instability Poor Appearance High cost added. Additional weight. Troublesome when frequency of changes are high. Additional cost on tooling. Cannot withstand high force. Less reliable for medium duty function. Cracked easily when dropped. Easily wear and tear after frequent use.
Value Engineering SG OMTI2014 V1CM
Page 68 Copyright © PSB Academy
6. Riveting the plastic base instead of plastic catch. 7. Change all metal parts to mild steel 8. Change the plastic base into sliding catch method. (refer to Figure 8) 9. Incorporate plastic cap at the bottom of the base for containing staple refill (refer to Figure 8)
Permanent attachment to the metal parts More Rigid Reduce cost. More staple Will not come out when dropped Can be changeable. Less prone to wear as compared to plastic catch Less material cost. Additional function. Reduce search for refill. Eliminate bringing staple along in container Reduce cost of staple container.
Additional cost. Base cannot changed Additional process. Rust easily Wear easily on moving parts Less rigid than galvanised steel Slight additional cost product.

CONCLUSION
The overall result of the project after evaluation had shown a cost saving of $0.59 and the stapler function performances was reinforced.
The intangible results will be:
Ease in refilling the staple with better gripping on the staple pusher.
The stapler will not break into 3 part when it dropped onto the floor.
User will not have to search for staples if they forgot to bring along a box of staple.
The plastic cap will act as a buffer to prevent the plastic base from cracking when it dropped onto the floor.
There will be no obstruction to user’s fingers when handling the stapler on the palm during filing of documents.
In conclusion, this project had built our knowledge of value engineering techniques. It not only discipline our taught, it also build up our teamwork during our course of group decision making
