Introduction

As software designers, it is important to build a user-friendly interface, to provide successful software.

Implementing Molich and Nielsen design heuristics, within the development area can provide a leading edge with other competitors.

In the following report, you will find how the Molich and Nielsen design heuristics can be implemented in the area of software design industry, how it can improve the product, and what heuristics means.  This will be run along side examples of Microsoft.


Heuristic Evaluation

To make an evaluation of a users interface, heuristic evaluation is a cheap and quick method to under take such task.

The most popular inspection method is heuristic evaluation.  This is done synthetically, of a user interface design for usability.  The whole aim of the heuristic evaluation is to identify problems that may occur with users, as part of the design process.  It involves set of evaluators to examine the interface, and are to judge the interface with the principles of the heuristics, such as Molich and Nielsen design heuristics.

Reason why a group of people are selected to judge this is an individual cannot be expected to find all the problems his self.  As this has been proven that different users do find different usability problems.  


Heuristics of Good Design (Molich & Nielsen)

You can avoid common design pitfalls, by following the Molich & Nielsen design heuristics.  This allows you to inspect, an interface usability problems with these principles.

The design principles are as follows:

  • Statements that have broad usability, which guides the design efforts of the developer.
  • Copied by evaluating common design problems across many systems

When doing the evaluation of the heuristic, the same principals are used for usability problems, here user involvement is not required, and you will able to catch many of the design flows.

There are advantages where the minimalist approach is used.  A few general guidelines can be used to correct majority of the users problems.  It is easily applied and easily remembered with little effort.  Discount Usability engineering is a cheap and fast way to inspect a system.  Double end users, double experts and usability experts can do this.

Ten Usability Heuristics

The following heuristics will be showed how they would benefit the product, and how it can be implemented with in the design of the product, the first nine were launched in 1990, and the 10th heuristic usability was launched in 1994, which included help, as a heuristic usability.


Use Simple and natural dialogue

You should use the user’s conceptual model.  Match the users task in every way possible, by minimizing the mapping between task semantics and interface, as shown below.

It is important to only present the exact information the user would need, bearing in mind “less is more”.  With a simple principle of less to learn would mean less to get distracted by therefore less errors would be made.

The information that is displayed should appear in natural order.  All related information should be clustered together, order the information appears should match users expectations.

Any information that is not needed should be removed or hidden due, to this would compete with information on users screen.
