QUALITY OF DESIGN ACCORDING TO DEMMING


-->
INTRODUCTION
William Edwards Deming was an American statistician, professor, author, lecturerandconsultant.  He taught top management how to improve design (and thus service), product quality, testing, and sales (the last through global markets) through various methods, including the application of statistical methods.
Quality is a perceptual, conditional and somewhat subjective attribute and may be understood differently by different people. Consumers may focus on the specification quality of a product/service, or how it compares to competitors in the marketplace. Producers might measure the conformance quality, or degree to which the product/service was produced correctly. In Deming's view, the consumer is by necessity the most important part of the production system: without a consumer, there is no reason to produce.  The question then becomes one of what the consumer needs (or what the consumer thinks he needs or wants).   The consumer is not, as Deming points out, always the one who pays the final bill: one or more middlemen may exist between the producer and the person actually paying for the product or service. The consumer is simply the end user of whatever product or service is being supplied.  Deming cites one important example of where this distinction is frequently lost in an anecdote regarding the review of elementary school readers produced by a publishing house. 
According to Deming Quality can be broadly classified into;
1. Quality of Conformance,
2. Quality of Design and
3.Quality of market and sales.




QUALITY OF DESIGN
Definition:
It is the level of effectiveness of the design function in determining a product's operational requirement (and their incorporation into design) that can be converted into a finished product in a production process. Quality of Design is extremely important, and it is said that design is only 5% of the product cost, but has a 70% influence on quality, manufacturability, serviceability, and general acceptance in the market. Customer focused organizations must continuously work on improving the Quality of Design; and improving the quality of design will also have a positive impact on the Quality of Conformance.  For example if the specifications of the mating dimensions and other parameters are not optimal, there is a high probability of not obtaining the desired final product parameters; so meeting the specified design itself becomes difficult.

 Reasons for quality design
1)      To be competitive by offering new products and services ahead of competitors.
2)      Make business grow and increase profits.
3)      Prevent defects that may occur during design process.
Design aspects
1)      Increase emphasis on customer satisfaction and increase pressure to be competitive.
2)      Increase emphasis on reducing the time needed to introduce a new product or service.
3)      Greater attention to the capabilities of the organization to produce or deliver the item.
4)      Increase emphasis on designing product and services that are user friendly.
5)      Increase effort to use less material for product and less packaging.

DESIGN PROCESS
This is a process that considers factors such as customer needs and expectation, new technologies, competition and government regulation. It must take into account its cost, target market and its expectedfunction.
Diagram below shows the following design processes:
             
a)Conception or need identification-this includes the market needs, employee suggestions, designer's ideas and customer requirement(basic needs).
a)      Feasibility study- here specification are shown to be achievable by mathematical calculations, preliminary drawing models or laboratory scale processes. New ideas are analyzed for feasibility and a question such as; will the product meet customers requirements? Is asked.
b)      Execution of the design-implementation of the design is done here. Design reviews are frequently conducted to identify and eliminate possible causes of manufacturing and marketing problems.
c)      Detailed engineering- Product is put in such a form that can be made within the organization and to the specification laid down.
d)     Production process, design and development- qualities are produced sufficient to check the design equipment and specification.
e)      Production evaluation and improvement- value analysis, value engineering and method study undertaken here.
f)       Product used and commercialization- capacity planning, production planning and control also need to be addressed.
g)      Market evaluation- after product has been commercialized; organization should undertake evaluation and follow-up so that any requisite changes can be addressed. This helps in continuous improvement.



                                                               
QUALITY OF CONFORMANCE
This is the level of effectiveness of the design and production function in effecting the product manufacturing requirement and process specification, while meeting process control limits, product tolerance and production targets.                                                                                Typically organizations spend a lot of resources to ensure quality of conformance, which includes operational controls and inspection.  Inspection and policing has become such a big activity because of noncompliance to systems and procedures.  I think while poor design quality could be due to lack of knowledge and competence, quality of conformance is more to do with discipline and attitude. Hence policing has become a major activity to meet quality requirements. I also think that this becomes a habit which evolves into a culture of being used to be policed to ensure that rules, procedures and systems are followed. This is evident not just in factories manufacturing products, but in almost all walks of life including the roads. On Indian road we see such a large police force deployed just to ensure compliance to traffic rules; I am not sure if any other country spends so much of resource for this activity. The level of policing is so high that at each traffic signal point we sometimes see a couple of constables and an inspector; and this seems to be quite normal for us. There is already a pretty good system of signal lights to control traffic, still why do we have police controlling the traffic? This is a clear case of resource being wasted in inspection or patrolling.  The resource used here can be put to better use; may be making improvement plans and better designs. 
 There is no doubt that for growth and progress the quality of design has to improve, not just for purpose of customer delight, but also to focus on Design for Assembly, Manufacturability and Serviceability. But first we must ensure there is conformance, and this has to be met with improved techniques rather than utilizing human resource in excess inspection, patrolling and policing.  In manufacturing for instance improved fixtures, computer controlled closed loop equipment, gauging and error- proofing is adopted as compared to inspection of finished goods. Even with good controls in place it is essential that there is adherence to systems and procedures and this calls for positive attitude and discipline. Following procedures with little intervention and policing brings in a disciplined culture and maturity to the system. 
                                                    
There must be a concentrated effort to bring about this change in the system and it is to do with human resource development. 
 The challenges are different depending on the nature of the business and the educational level of people being handled, for sure the most challenging is when the people involved is as vast and mixed as the public on the road; but every problem does have a solution. I think several things can be done to improve the situation on the road. Some things that come to my mind are:

1.  Public awareness campaigns.
 2.  Clear and attractive displays of rules at the junctions including in the local language
 3. Awareness drives at selected segments like educational institutes, offices, taxi and auto driver associations 
4. Collecting data and identifying the major offenders and focusing more on that group; for example if auto drivers are identified as the major rule breakers, then there must be specific awareness for that group 
5.  Involving public in the awareness campaigns
 6.  Display of accident data with photographs, if possible at specific junction 
7.  Heavy fines for breaking rules must also be imposed, but this should be only to bring in discipline initially and not the only way of control.

"The resource currently used to control traffic at signal lights can be used to carry out all these improvements, which will also add to their development and respect in society."

The same logic can be applied to any system to improve quality of conformance, and utilize resources more effectively, for improvement and progress of system and society.  
Quality of conformance is the degree to which the design specifications are followed during manufacturing. Again, the greater the degree of conformance, the higher the level of quality of conformance.

In software development, quality of design encompasses requirements, specifications and design of the system.
The requirements must be gathered formally and there should not be any ambiguity and must be complete in all respects. Specifications must be elaborated and defined formally. Design must follow the design and the resulting system meets its requirements and performance goals, conformance quality high.

QUALITY OF MARKET AND SALES.
Quality starts with marketing. Marketing establishes the true requirement for the product or service. These must be communicated properly throughout the organization in the form of specification.
Deming's points apply to any type and size of business. Service companies need to control quality just as much as manufacturing companies. And the philosophy applies equally to large multinational corporations, different divisions or departments within a company, and one-man operations.

Sales process engineering

Sales process engineering has been described as the systematic application of scientific and mathematical principles to achieve the practical goals of a particular sales process". Selden pointed out that in this context, sales referred to the output of a process involving a variety of functions across an organization, and not that of a sales department alone. Primary areas of application span functions including sales, marketing and customer service. Variations of this brief description are possible, but described as such, the discipline is consistent with other published definitions of engineering and its many well-established branches, but relatively new in its focus.


Quality Sales Culture
There are three parties (constituencies) that are affected by the culture you build.
  1. Clients - Your focus on making reasonable commitments and then driving over-delivery will pay offin a huge way. The Net Present Value of your client base is driven by retention rates and gross profitability. You can easily model the value of high customer satisfaction by raising your client retention rate by 5% and improving gross margins by 1%. This is the value of ensuring that your culture demands a high customer satisfaction rate. I dumbed down these numbers. You can achieve much better benchmarks if drive customer satisfaction into your sales culture. It will not only make them believers but their closing ratio's will be dramatically better.

2.Shareholders - This is the easiest constituency to satisfy or dissatisfy. If your Business Development Efforts focus on customer service delivery within a cross selling framework, and your sales efforts are highly disciplined around skill, will, execution and leadership it is nearly impossible to disappoint investors in your company. I do believe that investors have now learned that mid-term results trump short term returns.
3.Employees - Why bother? Because clients and shareholders will never get the best possible outcomes if your employees are distracted. Sales people and account managers should get all the direction & support they need to create healthy, profitable client relationships. People who are distracted by poor leadership, non-existent training or poor customer service attitudes will never be able to deliver to their potential.

TEAMWORK AND EMPLOYEE EMPOWERMENT


-->
Empowerment means giving people authority to make decisions based on what they feel is right, have control over their work, take risks and learn from mistakes, and promote change (Evans and Lindsay, 2008). Empowerment is the process of enabling or authorizing an individual to think, behaves, take action, and control work and decision making in autonomous ways. This means leaders and managers relinquishing some of their powers that they previously held in terms of decision-making. Empowerment diffuses decision making to employees so that employees make decisions regarding what they do and how they do it. Empowering employees is giving employees ownership of their jobs. Empowered employees are given ownership of the processes they are responsible for and the products or services generated by those services. Organizations may empower their employees by encouraging them to set their own goals, judge their own performance and take responsibility for their actions. Empowerment builds confidence in workers by showing them that the company has confidence in their ability to make decision on their own. Empowered employees take pride in their work and the resulting products or services produced by it. It helps generate a commitment to the organization and develop a sense of pride. It presents an opportunity to employees to develop them and advance their careers. It allows employees to use their skills and talents to the maximum, and hence promotes the spirit of self -determination.

The role of employee empowerment in total quality management (T.Q.M)
The basic philosophy of total quality management is to involve every employee in the organization along with its suppliers and distributers to improve quality and thus enhance customer satisfaction. Employee involvement is very important in any T.Q.M initiative, as it is a system wherein employees are encouraged to use their expertise and knowledge to suggest methods for improvements in their work areas. These suggestions could relate to improvements in the job, the product, the work atmosphere or the company as a whole. Many companies have ventured into a participation-style of management by involving employees in the problem solving and decision making processes. While the actual practice of employee empowerment varies across organizations, empowerment is based on the concept of job enlargement and job enrichment. Job enrichment involves increasing the depth of the job to include responsibilities that have traditionally been carried out at higher levels of the organization.

Benefits of employee empowerment
Some of the benefits of empowering employees include;
  Improved morale       
Involving employees in decisions and policy changes that directly affect their job while also empowering employees to be more autonomous greatly improves company morale at large.  

  Increased productivity
Quality management practices also translate into increased productivity

  Team cohesion
Employee empowerment fosters better relationships between employees and with their managers, as employees that are given more independence tend to form better working relationships.

  Innovation
Employee empowerment cultivates innovation as employees that have a stake in company growth and sustainability will offer more ideas and problem solving solutions when solutions arise.


Principles of employee empowerment


1) Demonstrate that you value people- your regard for people shines through in all of your action and words. Your goal is to ensure and show your appreciation for each person's unique value.
2) Share leadership vision- help people feel that they are part of something bigger than themselves and their individual jobs.
3) Share goals and direction- share the most common and important goals and direction for your group.
4) Trust people- trust the intention of the people to do the right thing, make the right decision, and make choices that still work.
5) Provide information for decision making- make certain that you have given people or made sure that they have access to all of the information they need to make thoughtful decisions.
6) Delegate authority and impact opportunity, not just more work- don't just delegate the drudge work,delegate some of the fun stuff too.

Role of teamwork
Definition of a team
A team is defined as a group of people with a common, collective goal. This goal aspect is very critical in the team. An example of teamwork succeeding over individualism is the No Name Defence of the Miami Dolphins of the National Football League during the early years of the franchise. In this team no member stood out above the others. In fact, although it was arguably the best defences in the league at the time, individual team members were not well known hence the name No Name Defence.
Teamwork is a fundamental element of total quality because it is organizations not individuals that produce products and provide services. This consequently makes peak performance and continual improvements are ground, not individual endeavors.
The Need for Teams
In the above example, the team's ability was more than the sum of the abilities of individual members. This is the major reason for advocating teamwork. The rationale for teamwork therefore is:
  Teams satisfy the human social need to belong
  It promotes better communication
  It multiplies the potential of individual members
  It produces positive peer pressure
Team excellence and performance
Teamwork is not a magic cure -all. Poorly run teams can do more damage to an organizations performance and corresponding competitiveness than having no teams at all. Thus, excellence is an overriding goal for the organization. This excellence is attributable to team leaders who posses the following characteristics:
v Trust -team leader should build trust among their team members and between themselves and team members as people will not work well with people they do not trust
Mutual support- individuals depend on each other to get the jobs of the team done. Members should therefore be supportively willing and able to assist each other in achieving peak performance.
v Accountability-self assessment of team performance is a constant as is continual improvement
Reinforcement- wise team leaders reinforce team positive behaviors and attitudes by recognizing and rewarding them.


Building teams and making them work
Part of building a successful team is choosing team members wisely. It involves strategies for selecting team members, naming officers, creating a mission statement and developing collegial relations among team members.

Makeup and size of members
Teams should be composed of those people who are most likely to able to satisfy the team's mission efficiently and effectively. The appropriate makeup of a team depends in part on the type of team in question (whether it is departmental improvement, process improvement, or task force or project oriented). Departmental improvement teams such as quality circles are made up of employees of a given department. However, process improvement teams and task forces typically cross departmental lines.
The membership of such teams should be open to any level of employee-management,    supervisors and hourly wage earners. A good rule of thumb is that the greater the mix, the better.

Choosing team members
When putting together a team, the first step is to identify all potential team members. This is important because there will often be more potential team members than the number of members actually needed (12 members maximum). After the list has been compiled, volunteers can be solicited and actual team members selected from among those who volunteer, care should be taken to ensure a broad mix.

Developing Collegial Relationships
A team works most effectively when individual team members form positive, mutually supportive peer relationships. These are collegial relationships, and they can be the difference between a high-performance team and a mediocre one. The following are strategies for building collegial relationships among team members:
  Help team members understand the importance of honesty, reliability and trustworthiness
  Help team members develop mutual confidence in their work ability
  Help them understand pressures to which other team members are subjected
Effective teamwork is built on competence, trust, communication, and mutual support and resources should be channeled to improve these.

Promoting Diversity in Teams
The workplace today is dominated by women and minorities coming from different cultures and backgrounds. Consequently, they are likely to have different values and outlooks. This situation can be good or bad, depending on how it is handled. Dealing with diversity in a way that makes it a strength is called managing diversity.
When diversity is properly managed, impediments to women and minorities that exist in workplaces can be eliminated. By working together in well-supervised teams that include women and men, young and old, minorities and non- minorities, employees can learn how to realize the full potential of diversity. Diversity in teamwork can be promoted by applying the following strategies:
v  Continually assess circumstances. Is communication among diverse team members positive? Do bias and stereotyping exist among team members? Do minorities and nonminority with comparable jobs and qualifications earn comparable wages? Factors that might undermine harmonious teamwork should be anticipated, identified and handled.
v  Give team members opportunities to learn. Education and training aimed at promoting sensitivity to and appreciation of human differences should be provided. Such training should also help team members overcome the stereotyping assumptions that society in general seems to promote.
Character traits and team work
Character building is part of a team building program. Participants in each group contribute to team success or failure. There is a strong correlation between composite data of a successful group and an unsuccessful group. The traits of teamwork are as follows.
1.       Honesty and integrity-to build trust, team members must be honest to each other. Honesty is a cornerstone of trust and trust is a cornerstone of teamwork.
2.       Selflessness-this character trait means that the people are willing to put the team interests ahead of their own. A team can move only as fast as the slowest member. This means that there will always be a member who will get out in front of the pack unless they rein themselves in.
3.       Dependability-people who are dependable consistently do what they are supposed to do when they are supposed to do it and how they are supposed to do it.
4.       Enthusiasm-the concept of team spirit isreal.people that is enthusiastic about their work typically do it better.
TEAMS ARE COACHED, NOT BOSSED
If employees are going to be expected to work together as a team, managers and supervisors are to realize that teams are coached-they are not bossed.
Bossing in traditional sense involved planning work, giving orders, monitoring programs and evaluating performances. Coaches on the other hand are facilitators of team development and continually improved performance. This philosophy is translated into every day behavior in several ways. These include:
         Coaches give their team a clearly defined character.
         Coaches make team development and team building a constant activity.
         Coaches are mentors.



MENTORING
Good coaches are mentors. This means they establish a helping, caring, nurturing, relationship, with team members. Developing capabilities of team members, improving the contribution individuals make to the team and helping team members advance their career. According to David Cottrell, effective mentors help team members by:
         Developing their job-related competence.
         Building character.
         Teaching them the corporate culture.
         Teaching them how to get things done in the organization.
         Helping them understand other people and their view point.
   MUTUAL RESPECT
It is important for team members to respect their coach, for the coach to respect his or her team members, and for the team members to respect each other. Respect is built on the following factors:
1.       Trust made tangible-trust is built by setting the example, sharing information and explaining personal motives.
2.       Appreciation of people as assets-appreciation of people is shown by respecting their thoughts, feelings, values and fears.
3.       Communication that is clear and candid-communication can be made clear and candid if coaches observe and listen.
REWARDING TEAM AND INDIVIDUAL PERFORMANCE
An organizations attempt to institutionalize teamwork will fail unless it includes implementation of an appropriate compensation system: in other words if you want teamwork to work, make it pay. The most successful compensation systems combine both individual and team pay.
COMPONENTS OF THE MOST SUCCESSFUL COMPENSATION SYSTEM
                                                   I.            Base individual compensation
                                                 II.            Individual incentive compensation
                                               III.            Team-based incentive compensation.
    
 STRUCTURAL INHIBITORS OF TEAMWORK
In an article for Quality Digest, Michael Donovan describes some of the structural inhibitors to effective teamwork that are commonly found in organizations:
           I.            Unit structure-teams work best in a cross-functional environment as opposed to the traditional functional-unit environment.
         II.            Accountability-in traditional organization employees feel accountable to management. This perception can undermine teamwork.
       III.            Unit goals-traditional organizations are task oriented and their unit goals reflect this orientation.
Resolution strategies for team conflicts
Conflict will occur in even in the best teams, even when all team members agree on a goal they can still disagree on how best to accomplish it. Team leaders and members can apply these strategies for preventing and resolving team conflicts;
         Plan and work to establish a culture where individuality and dissent are in balance with teamwork and cooperation.
         Establish clear criteria for deciding when decisions will be made by individuals and when they will be made by teams
         Don't allow individuals to build personal empires or to use organization to advance personal agenda.














CONCLUSION
In the above discussion it can be concluded that empowering employees is empowering the organization, as such employee empowerment should be totally and collectively embraced to ensure that the organization is steered to greater and maximum success in the achievement of its goals and objectives.
Teamwork also ensures collective responsibility within the organization and eliminates back passing.
