Network Design Principles: Design by Committee

      Comments Off on Network Design Principles: Design by Committee

Significant engineering designs are rarely the result of one person’s effort. Network design performed by a single person may be acceptable if user requirements are simple and the possibility of getting things wrong is low or easily fixable. Otherwise, the design effort should involve a group of experts and relevant… Read more »

Network Design Principles: Cost-benefit

      Comments Off on Network Design Principles: Cost-benefit

A design can be evaluated using the cost-benefit principle, and it will be considered good if the benefits outweigh the cost. From a designer perspective, a cost-benefit analysis can assess the financial returns associated with adding a design feature. The designer should also evaluate benefits and costs from the user’s… Read more »

Network Design Principles: Consistency

      Comments Off on Network Design Principles: Consistency

The consistency principle states that systems are more usable and learnable when similar parts are expressed in similar ways [Lidwell 2010]. Consistency in network design can be applied to appearance (e.g. network documentation) or to functionality (e.g. device configuration). Internal consistency refers to consistency with other components in the system… Read more »

Network Design Principles: 80/20 Rule

      Comments Off on Network Design Principles: 80/20 Rule

The 80/20 is also known as the Pareto Principle. It refers to the work of Vilferdo Pareto that describes the relationship between the elements that make up a whole and the influence that each element exert on the whole. The 80/20 rule is observed in all large systems, including data… Read more »

Network Design Principles

      Comments Off on Network Design Principles

Design principles are widely applicable laws, guidelines, biases and considerations that designers use to guide their decision-making process. Engineers use some of these principles to design products that meet the users’ requirements. In a series of posts, I describe briefly one design principle that is applicable to the design of… Read more »
