Design Methods for decision-making

Introduction
The figure of designer is a hybrid between the artist, the mathematician an the scientist, but he can not be identify with nobody of this three figures (Jones, 1992). In fact the designer, to take decisions within a project, applies both creative and mathematical methods.
The aim of this essay is to demonstrate if these two approaches to the design are more useful and utilized in the effective project or in commercial environment. Thus, to understand what is the reason for which they are used, it is decided to analyse two creative methods, brainstorming and mood board, and two mathematical, evaluation matrix and QFD.
What is resulted from the analysis of these two approaches to the design it is that the creative methods are really used by the designer for the project, while the mathematical methods are more useful for commercial purposes and in business environment.

Creative methods
Brainstorming
Brainstorming is a technique very utilized in the design environment, because it allows to maintain wide the project area and because it is a method which can be used in every step of the design process. The word itself can guess what is the function of this method: to produce many ideas quickly (Jones, 1992). Osborn, the inventor of this technique, has dictated very precise rules (Cross, 1994):
- No criticism is allowed during the session
- A large quantity of ideas is wanted
- Seemingly crazy ideas are quite welcome
- Keep all ideas short and snappy
- Try to combine and improve on the ideas of others
People, who will participate in brainstorming, are another key of this method, because as Castiglioni (1995) said: " Un progetto di design è frutto di uno sforzo comune con specificità differenti", which means that a design project is the result of a joint effort with different specificities, in fact they

Research Design Methods Case Study

...Question 1 Many organizations frequently rely on the insight of consultants to assist them in identifying areas of opportunity, making highly impactful decisions, and gaining additional insights as to the forthcoming direction of their industry. Some of the largest and most reputable consulting firms, such as Booz Allen and McKinsey, work on a global scale with internal divisions that specialize in a number of varying industries. The concept of consultants has been of great debate for many years, as some believe that if there is good management in place, they should be able to lead their organization appropriately without the help of expensive teams from the outside. However, one must remember that a great deal of what makes the daunting price tag of consultants an easily justifiable expense is the extraordinary weight the opinion of outside consultants carries with key influential decision makers. A Forbes magazine article on the topic says, “It really is often about being able to say “XYZ Consultants Inc recommend we do this” as that carries more weight in the internal arguments than “I say we do this” (Worstall, 2012). As a manager at a life insurance company, there a a number of things I would be looking for in the business report I received from the consulting firm I hired before I deem their findings valid. I would first need to understand the intent of the research contained in the business research report. For instance, I would view the findings from one point of...

Poorer development in infants and toddlers has been directly linked to maternal depression. Furthermore, infants of mothers who have depressed mothers tend to talk less, they engage in little play and lag behind on standardized language and mental development scales (Campbell et al, 2004). The aim of this research was to test the interpersonal psychotherapy of parenting enhancement to reduce depression of low income mothers of infants and toddlers. This study used a two group repeated measures design which was randomized. Mothers who were given the IPT + PE plus EHS enrichment were compared with mothers getting attention control health education plus EHS enrichment. The IPT + PE and ACTAU conditions were delivered over a 20 week period. Data were collected at four points: at baseline before randomization (T1), partway through the intervention (T2: 14 weeks), after completion of the intervention and termination with the nurse (T3:22weeks), and 1 month after all intervention stopped (T4: 26 weeks).

...Abstract The objective of this paper is to explore the fundamental circumstances to sustain the validity of prosocial behavior using experimental methods. The focus is on psychological issue of prosocial behavior, and evaluated these concepts using a descriptive method design. In doing so; this paper describes the sample populations, the experimental methods, and provide a speculation on the expectation of the outcomes of prosocial behavior in these scenarios. In addition, this paper further discusses the established sequence of necessary conditions to support the validity of prosocial behavior in reference to bystander effect. In conclusion, relating the conditions of the survey for reliability and to evaluate whether or not the methods discussed measures and are confirmed through the internal consistency, test-retest reliability, and support an inter-source agreement. Experimental Method Design The bystander effect is a psychological episode in social psychology that connects with incidents when individuals refuse to assist in an emergency situation when others are nearby. In the past, the probability of help as been believed to be involving oppositely affected variables comparable to the number of bystanders, for instance, the more bystanders, the least likely anyone will help. John M. Darley was the first social psychologist to make obvious the bystander effect. In this experience, an emergency situation is thespian, and the participants are alone...

Data Design Methods

...Data Design Methods Introduction Many organizations and companies rely on databases to run their operations and achieve competitive advantage. Database design refers to the different parts of the design of an overall database system. It can be thought of as the logical data structures used to store data, and the forms and queries used as part of the overall database application within the database management system (Wikipedia.org). The paper focuses on database design methods and steps that can be taken to achieve a good design structure that avoids redundancy, duplicate data or the absence of required data. The need to understand database models Databases are important to the organizational setting. Databases allow organizations to share data across multiple applications and systems. Organizations build several databases each one sharing data with several information systems. This is because it is almost impractical to build one database to meet an entire organization’s needs. Therefore data design is critical to the consistency, integrity and accuracy of the data in a database. A database that is improperly designed will make it difficult to retrieve certain types of information. Besides, there is the risk that searches will produce inaccurate results or information that may have potential damaging effects on a company's bottom line. Inaccurate database may also affect the daily operations of a business and its future direction. A good database addresses the informational...

...two distinct methods of software development. The Waterfall model can essentially be described as a linear model of software design. Like its name suggests, waterfall employs a sequential design process. Development flows sequentially from start point to end point, with several different stages: Conception, Initiation, Analysis, Design, Construction, Testing, Implementation, and Maintenance. The Agile method proposes an incremental and iterative approach to software design. It was essentially developed in response to the limitations of Waterfall, as a way to give designers more freedom. The design process is broken into individual models that designers work on. There is no pre-determined course of action or plan with the Agile method. Rather, designers are free to respond to changes in requirements as they arise and make changes as the project progresses. Agile is a pretty new player to the development game. However, it has made substantial gains in use and popularity in the last couple of years. Agile: The Pros Agile offers an incredibly flexible design model, promoting adaptive planning and evolutionary development. Agile might be described as freeform software design. Software developers work on small modules at a time. Agile can be especially beneficial in situations where the end-goals of projects are not clearly defined. For example, if you are working with a client whose needs and goals are a bit hazy, it is probably worthwhile to employ the Agile method. The client’s...

Design Thinking

...DESIGN THINKING: CHARACTERISTICS AND PROMISES Arkin Efeoglu1, Charles Møller2, Michel Sérié3, Harry Boer2 1 2 SAP Germany Aalborg University, Denmark 3 SAP Germany arkin.efeoglu@sap.com ABSTRACT This paper analyses a variety of Design Thinking methods to identify a governable pattern that is required to roll out Design Thinking as mindset in a multi-national company. A comparative analysis is essential to unveil focal points that lead to this organizational mindset transformation. Hence, a thorough understanding of the method and its core values may avoid uncoordinated innovation capabilities. Ultimately innovation will not be an R&D topic in an organization anymore but become part for every employee’s job, irrespective of his or her position. Keywords: Design thinking methods and characteristics, Review 1. INTRODUCTION A number of new innovation methods have emerged during the past two decades with an increasing interdisciplinary collaboration between the engineering, economic and social sciences. In spite of this, it is still a challenge to develop and introduce new innovations. One approach that increasingly makes its way to businesses of all sizes is called Design Thinking. This approach seems to be more promising to operationalize the innovation capabilities of a company (Brenner and Witte, 2011). Design Thinking is a human-centered problem solving method that mostly leads to radical innovative solution in terms of the feasibility, desirability...

Explain the features which could enhance the quality in product design at the conceptual stage. 1.0 Level of Total Quality Management Adoption The Six different levels of TQM implementation, this includes uncommitted, drifters, tool pushers’ improvers’ award winners and world class. According to them, these stages do not necessarily represent the stages through which organizations pass on their TQM journey. These levels are to help organization in identifying their weaknesses and proffering solutions to them through the use of continuous improvement. (Dale and Lightburn 1992) 1.1 Uncommitted This stage represents organizations that have not started a formal procedure of quality improvement. Organizations in this stage view quality improvement as an added cost and thus have no investment in quality improvement program such as training of employees. Organizations in this stage are termed uncommitted because they are not aware of the benefit of quality improvement and lack an appropriate quality improvement plan. The management of these organizations is characterized by an emphasis on return of sales and net asset employed. For example: non-attendance the meeting, failure to respond to requests the data, and not doing what they had agreed to do. Other common features of this level include: • A major concern for meeting...

System

...A system is a set of interacting or interdependent components forming an integrated whole or a set of elements and relationships which are different from relationships of the set or its elements to other elements or sets. The elements of a system are: * Input and output * Process * Control * Feedback * Environment * Boundaries and interface There are 4 System Development Approaches: 1. Prototyping Development 2. Rapid Application Development 3. Joint Application Design 4. Participatory Design 1. PROTOTYPING DEVELOPMENT: Software prototyping refers to the activity of creating prototypes of software applications, i.e., incomplete versions of the software program being developed. In this a prototype is made first and based on it final product is developed. A prototype is a model or a program which is not based on strict planning, but is an early approximation of the final product or software system. This type of System Development Method is employed when it is very difficult to obtain exact requirements from the customer. While making the model, user keeps giving feedbacks from time to time and based on it, a prototype is made. Completely built sample model is shown to user and based on his feedback; the SRS (System Requirements Specifications) document is prepared. After completion of this, a more accurate SRS is prepared. 2. RAPID APPLICATION DEVELOPMENT: Rapid application development (RAD) is a software development methodology that...

While enhancing thermal characteristics, the solid–liquid mixtures present an unavoidable disadvantage in terms of pumping cost for economic operation of thermal-fluid systems. In addition, there is a lack of agreement between experimental data provided in the literature. The present work found that there would be no comprehensible design strategy in developing nanofluids. In this work, the Axiomatic Design (AD) theory is applied to systemize the design of nanofluids in order to bring its practical use forward. According to the Independence Axiom of the AD theory, the excessive couplings between the functional requirements and the parameters of a nanofluid system prevent from meeting the functional goals of the entire system. At a parametric level, the design of a nanofluid system is inherently coupled due to...
