Characteristics, Features And Modules Of An ERP System

Characteristics And Modules Of An ERP

Knowing the characteristics of an ERP is essential, it is complex and complete software packages that integrate various functions and resources of the company. An ERP system comprises transversal functions that cannot be encapsulated in other information systems, such as data synchronization, standardization, complexity and modularity of the system.

Over the years, new functional features have been added to the ERP software evaluation process. As has been said, ERP is a complex and complete product that integrates functions and resources. As such, it must provide secure, reliable and real-time information. In addition to modularity, the execution of basic functions, the synchronization of information and other traditional requirements, there are a number of characteristics of an ERP that must be evaluated.

Requirements management of an ERP

Requirements Management establishes what the ERP system must do in terms of processes, queries, reports, alarms, interfaces, security restrictions and some other elements that the organization needs. So if they are not identified correctly, the software will not provide the user with the expected functionality. Furthermore, if they are not fully and clearly determined, the scope will not be known and it will not be possible to estimate the real size of the ERP Project.

Characteristics of an ERP


Functionality is the ability of the software to provide the resolution of requirements expressed as user needs. To evaluate this characteristic, it has been subdivided into four sub-characteristics:

  1. Precision
  2. Adequacy
  3. Interoperability
  4. Security

Adapting the functionality of an ERP system should provide a solution, among others, to known requirements such as:

  1. Financial processes
  2. Human resources management
  3. Supply chain processes
  4. Manufacture process
  5. Customer service processes

It should also cover specific processes when used under specified conditions.


Reliability is the ability of the software to provide services with a certain level of performance under the conditions established in a defined period of time. Reliability has three sub-characteristics:

  1. Maturity
  2. Fault tolerance
  3. Recovery

Reliability can be defined in other words: the probability of a failed ERP implementation due to a given problem within a period of time.

Usability or ease of use

Ease of use is the ability of the software for users to learn, use, and find attractive when used under specific conditions. The ease of use includes three sub-features:

  1. Understanding
  2. Learning
  3. Operability


Efficiency refers to the ability of a system to provide a certain performance in relation to the resources used, under established conditions. To measure it, three sub-categories have been established:

  1. Behaviour
  2. Use of resources
  3. Compliance

Ease of maintenance

Ease of maintenance is the ability of the software to be modified with minimal effort. It is composed of four sub-characteristics:

  1. Ease of analysis
  2. Ease of changes / modifications
  3. Stability
  4. Ease of testing


It is the ability of the software to be transferred from one environment to another. Therefore, the management software must be able to run on different operating systems, applied in different departments or organizations and under different types of hardware. Portability includes three sub-features:

  1. Adaptation
  2. Installation
  3. Co existence


The ERP system is a set of functional models with modules, each of which has its own functions. In order to perform a particular function, it is required that the data can be exchanged between modules or with external applications. In other words, compatibility refers to the ability of the ERP system modules to exchange data with each other and with other applications.


The complexity of an ERP is due to the interaction between the different modules. It is necessary to solve the complexity both at the level of development and maintenance as well as in the need of the end user to move between different modules.


All modules should be able to be implemented according to the needs of each of the clients and compatible with their resources.

Re usability

It is defined as such as the ability of the software code to be used in one project or another without the need for a new development. The reuse capacity is valued for different reasons, among which the following stand out:

  1. Shorter period of time to develop
  2. Saving of resources
  3. Tested and validated functions, ready to use
 Each sub-characteristic (such as adaptability) is divided into attributes. An attribute is an entity which can be verified or measured in the software product. The attributes of the Characteristics of an ERP are not defined in the standard, since they vary between different software products. The best way to ensure that the ERP to be implemented meets the business requirements is through a software evaluation and selection process.
