Attribute approach performance management

The three most common approaches are the categorical system, weighted-point average system and the cost-based system. The categorical system is the most subjective technique since it does not differentiate between the weights of the attributes considered. The weighted-point average system overcomes this drawback by assigning weights to each attribute.

You may have had to write tones of code to validate your business objects without taking advantage of attributes. The value of attributes comes when you need to apply the same rules on a number of properties, and the only thing you have to do is to decorate your property accordingly.

NET compiler enables us to richly embed metadata into an assembly, which can be accessed at a later time by using Reflection.

Attributes are decorative clauses that can be placed on classes, interfaces, methods, assemblies, modules, or other items. They become part of the assembly metadata, and can be used to assign rules to the compiler or to enable developers to reuse code to perform various operations including validation, tracing, and type conversion.

Attributes are inherited from the System. In our case, we would like to see how we can build our own custom attributes which we can use to make business object validation easier.

The usability of attributes would surely save you time, code, and the stress of having to individually validate each property of a business object.

The business object Consider a business object called Person, which we have decided inherits from the base class EntityObject. We have made the base class to implement the IEntityObject interface although it in not vital for this article.

Add new Error this, "Person", "A person cannot be 25 years of age!

Save method, which is provided by the base class, I validate the object. There are other approaches you may use, e. I have decided to defer validation to the end because the process involves Reflection, which can be expensive. We will begin with the [Required] attribute, and I should quickly ask you to note that the actual class name is RequiredAttribute, and.

NET lets you write it nicely as [Required] instead of [RequiredAttribute] although it will still work. It enables you to determine or restrict where the attribute may be used, and in my example above, we can only use the Required attribute on properties.

The AttributeTarget is an enum in which you can choose the scope of where this attribute can be used. You can use the AllowMultiple parameter of the AttributeUsage to determine whether the same attribute can be used more than once on the same target. In this case, we can have the [Required] attribute only once on a property.

Attributes can only have constants. The Business Object Base I decided to place a public Errors collection which will keep the errors encountered during validation. I also added event handlers that can be triggered when the validation method is executed. This enables hijacking the validation process if necessary, and inject validation rules after the object has been created.

The Validate method is virtual, and therefore can be overridden to allow custom business rules. This is what you would use to ensure that a male person would not have a boolean Pregnant property set to true.

Performance appraisal is a management tool which is helpful in motivating and effectively utilizing human resources.

Introduction

Assessment of human potential is difficult, no matter how well designed and appropriate the performance planning and appraisal system is. Based on the more current partnership approach, several techniques are used by companies to evaluate suppliers and measure performance.

The first step in implementing any of the techniques being discussed is to determine the attributes that should be considered. The Attribute Approach — The attribute approach to performance management focuses on the extent to which individuals have certain attributes (characteristics or traits) believed to be desirable for the company's success%(2).

The attributes assessed by the Caliper Profile are defined below, accompanied by brief explanations of the significance of a high or low score on each attribute.

While all attributes are considered important, please note that the attributes that most.
