As adjectives the difference between concurrent and sequential is that concurrent is happening at the same time; simultaneous while sequential is succeeding or following in order. Sequential engineering is the term used to describe the method of production in a linear format. Required fields are marked *. Defining features of these designs are reported along with quality control methods, and ethical concerns. Purpose: A phase III study was performed to determine whether concurrent or sequential treatment with radiotherapy (RT) and chemotherapy (CT) improves survival in unresectable stage III non-small-cell lung cancer (NSCLC). They are usually not concerned with how the product will be manufactured or assembled. Sequential engineering is the term used to explain the method of production in a linear system. The designers design the product's form, fit, and function to meet all the requirements, and pass on the design to the manufacturing department. Both product and process design run in parallel and occur in the same time frame. Basic Characteristics . Both process and product design run in serial and take place in the different time. Sequential engineering is a system by which a group within an organization works sequentially to create new products and services. Since oil is a liquid it has the tendency to 'leak' through every gas/slot it finds during movement. NO Sequential Transformative Designs II. These physical components are operating simultaneously. dsd(44) ⢠11k views. Thank you For Visiting. The concurrent engineering is a non-linear product or project design approach during which all phases of manufacturing operate at the same time - simultaneously. incurs cost, and therefore the resulting product is costlier than what it was originally thought to be. Mixing Methodologies [PowerPoint Slides]. Contribute! Concurrent Designs a. Concurrent TRIANGULATION Design b. Concurrent NESTED Design c. Concurrent TRANSFORMATIVE Design Adu, P. (2013).

What is a sequential design A) Both strands occurring in one simultaneous phase. Key Words: Mixed-Methods Studies, Quantitative Research, Qualitative Research, Concurrent Strategies, I am planning to use a mixed method design, initially I was looking at sequential explanatory but then I felt concurrent nested/embedded will be more ideal for my study. As seen in the figure, sequential engineering begins with customer requirements and then progresses to design, implementation, verification and maintenance. Traditionally, design has been carried out as a sequential set of activities with distinct non-overlapping phases. These needs are converted into product requirements which are passed on to the design department. He also likes to write articles related to the mechanical engineering field and tries to motivate other mechanical engineering students by his innovative project ideas, design, models and videos. SEQUENTIAL VS. design choices which involve a range of sequential and concurrent strategies. Problems and inconsistencies in the designs are therefore, detected when the product reaches into the later phases of its life-cycle. This leakage of... Slotter Machine - Types, Parts, Operations, Diagram, Specification. The market share is lost because of the delay in product's introduction to market, and customer faith is lost. Each phase receives the output of the preceding phase as if the output had been thrown over the wall. With today's marketplace becoming more and more competitive, there is an ever-increasing pressure on companies to respond quickly to market needs, be cost effective, reduce lead-times to market and deliver superior quality products. Both process and product design run in serial and take place in the different time. The various steps are done one after another, with all attention and resources focused on that single task. The concurrent engineering is a non-linear product or project design approach during which all phases of manufacturing operate at the same time - simultaneously. The single-phase timing of this design is the reason it has also been referred to as the âconcurrent triangulation designâ (Creswell, Plano Clark, et al., 2003). The 'Sequential Engineering vs Concurrent Design and Manufacturing' figure shows sequential engineering on the left and concurrent design and manufacturing on the right. Save my name and email in this browser for the next time I comment. Behav. Concurrent engineering is a method by which several teams within an organization work simultaneously to develop new products and services and allows a more stream lined approach. In such an approach, the life-cycle of a product starts with the identification of the need for that product. In multistrand designs, either the strands are parallel (concurrent mixed model design) or sequential (sequential mixed model design, in which inferences of one strand lead to questions of the next strand) or the data are converted and analyzed again to answer different questions (conversion mixed model design). needs to fit the type of mixed methods design in the study. Product and process are closely coordinated to achieve optimal matching of requirements for effective cost, quality, and delivery. Sachin is a B-TECH graduate in Mechanical Engineering from a reputed Engineering college. In such an approach, the manufacturing department, for example, does not know what it will actually be manufacturing until the detailed design of the product is over. In terms of sequencing, mixed method designs can either be concurrent or sequential. 1. Topic: Introduction to VHDL. C) One strand occurring prior to and informing the second strand. Sequential Designs a. Sequential EXPLANATORY Design b. Sequential EXPLORATORY Design c. Sequential TRANSFORMATIVE Design 2. Currently, he is working in the sheet metal industry as a designer. In this article, I argue that using a complete method with a supplemental component, both from the qualitative para-digm, is a legitimate form of mixed method design.1 I If What you looking for is not here, you may send a request to modify articles, Notes, and Content modification, Feedback, Suggestions here (Team will reply as early as Possible ): Contact Form or Using WhatsappÂ, © 2021 Copyright Learn Mechanical Engineering.

The type of logic, which can be sequential or combinational. sequential and concurrent engineering With today's marketplace becoming more and more competitive, there is an ever-increasing pressure on companies to respond quickly to market needs, be cost effective, reduce lead-times to market and deliver superior quality products. to research that uses both qualitative and quantitative meth-ods, other researchers concede that mixed methods is a term that may apply in within-paradigm research. The definition of Sequential as per the new Oxford American dictionary: Forming or following in a logical order or sequence: series of sequential steps. Anal. Sequential and Concurrent Engineering. Oil under pressure is moving in every hydraulic circuit. Concurrent engineering is a method by which several groups within an organization work simultaneously to create new products and services.

The slotter or slotting machine is also a reciprocating type of machine tool similar to a shaper. Both product and process design run in parallel and take place in the same time. Illustration of Mixed Methods Research Designs and Key Design Features A. In concurrent engineering, various tasks are handled at the same time, and not essentially in the standard order. In concurrent engineering, different tasks are tackled at the same time, and not necessarily in the usual order. Process and Product are not matched to attain optimal matching. In addition, there is a continuous feedback between these life-cycle phases so that the conflicts are detected as soon as possible. Your email address will not be published. Sequential engineering is a system by which a group within an organization works sequentially to create new products and services. Decision making done by only group of experts. Decision making involves full team participation and involvement. Subject: Digital System Design. However, it is not known whether sequential or concurrent delivery of these therapies is the optimal combination strategy. The designers are responsible for creating a design that meets all the specified requirements. The completion of a previous life-cycle phase is not a pre-requisite for the start of the next life-cycle phase. Mixed methods research takes advantage of using multiple ways to explore a research problem. The team often consists of product design engineers, manufacturing engineers, marketing personnel, purchasing, finance, and suppliers. The essentials of action research design follow a ⦠To understand the difference between the concurrent statements and the sequential ones, letâs consider a simple combinational circuit as shown in Figure 1. Useful resources and exemplary study references are shared. The moment they are powered, they will âconcurrentlyâ fulfill their functionality. 2) Exploratory sequential design. It generally involves the concurrent, but separate, collection and analysis of quantitative and qualitative data so that the researcher may best understand the research problem. The sequential engineering is a linear product design process during which all stages of manufacturing operate in serial. 1) Concurrent design (triangulation): The qualitative and quantitative components are deployed simultaneously and their results are compared. Statistics of Mixed Methods Design (1986 & 2000) B. Introduction to Seals : Process and Product are not matched to attain optimal matching. This is due to the ability of the non-concurrent design to avoid the practical limitations of the concurrent design and to avoid the practical and theoretical limitations of reversal designs. The whole process becomes iterative and it not until after a lot of re-designs has taken place that the product is finally manufactured.
