What is IT maintenance?

IT maintenance is certainly defined as the maintenance of IT equipment. However, this activity covers a series of other tasks, which vary according to the state of the equipment.

Definition of computer maintenance

Computer maintenance refers to the maintenance of computer equipment to ensure its proper functioning. This mission is generally carried out by IT service companies, the ESN, or Digital Service Companies. These companies can provide their services on site or remotely.

IT maintenance includes all the actions necessary for the functioning of the IS, whether it be to maintain or restore it. These actions can be regular or occasional:

  • backup of critical company data ;
  • migration of IT solutions
  • management of user rights;
  • messaging system configuration;
  • network administration;
  • installation and updating of software;
  • checking the status of the computer system and hard disks;
  • replacement of malfunctioning equipment;
  • equipment buy-out;
  • maintenance of inventory terminals, point-of-sale terminals and printers: Codeo’s speciality in terms of computer maintenance
  • cybersecurity assistance, including WiFi, firewall, antivirus and server management.

What is the purpose of IT maintenance?

IT maintenance has several objectives:

  • To maintain the performance of the equipment within 3 to 7 years of its deployment. This is particularly useful once the manufacturer’s warranty has expired;
  • Extend the life of your IT equipment;
  • To carry out the updates necessary for the continuity of the company’s activities;
  • Adapting computer equipment to software and technological developments and to changes in cyber threats;
  • Correcting any damage encountered.

The different types of IT maintenance

IT maintenance must guarantee the availability of applications, as well as the long-term performance of the IT equipment. It is therefore organised into 3 categories of maintenance: preventive, corrective and evolutionary.

1 / Preventive maintenance

Preventive computer maintenance consists of avoiding the appearance of problems. It can concern the computer security of the park, but also the improvement of its performance. Preventive interventions can be organised on a more or less regular basis, depending on needs. 

This type of computer maintenance therefore concerns both antivirus software and software updates. It also includes firewall management, temporary file cleaning and hard disk defragmentation.

Preventive maintenance also concerns hardware. As part of a preventive intervention, a technician can revise the equipment, clean it, make improvements to the settings to change parts likely to cause breakdowns in advance.

2 / Corrective maintenance

Carrying out corrective or curative maintenance means repairing equipment or software. These are one-off operations carried out when the equipment is no longer working or when it is subject to a computer virus. Corrective maintenance of information equipment takes two forms:

  • palliative maintenance: the IT maintenance provider carries out a temporary repair of the damage. Objective: to maintain the operation of the IS in the short term, to ensure the continuity of the company’s activities;
  • curative IT maintenance: repairing the faulty equipment so that it returns to its initial state.

3 / “Evolutionary” maintenance

Evolutionary maintenance consists of supporting the computer equipment over time. It may involve offering new hardware or software tools to users, based on the latest technological developments. Evolutionary maintenance also includes system updates and upgrades of the computer equipment.

3 levels of maintenance depending on the complexity of the IT problem

When a company outsources its IT maintenance, it can benefit from different levels of user support. A user who contacts the helpdesk of the service provider company exchanges with technicians. These technicians are responsible for :

  • identify the problem;
  • classify it according to a level of seriousness
  • open a “helpdesk ticket” describing the problem
  • draw up a list of actions to be taken to “close the ticket”, i.e. resolve the customer’s problem.

The second step, which consists of classifying the problem by degree of seriousness, leads in fact to prioritise the ticket according to 3 levels of maintenance:

  • The first level refers to “easy” IT maintenance. This may involve, for example, providing remote assistance to a user who is unable to use a software package. First-level maintenance covers basic faults that do not need to be escalated.
  • Level 2 IT maintenance concerns incidents that block the user and require further technical exploration. Technicians may need to contact software suppliers or equipment manufacturers. Generally, this type of problem cannot be resolved remotely. It involves a return to the workshop for testing and a full technical diagnosis. The team of technicians involved has a more in-depth knowledge of the various IT environments.
  • Level 3 IT support is deployed either on site or in the workshop. It concerns a critical incident for the client company, likely to threaten the continuity of its activities. This is an emergency, handled by experts. A replacement of the out-of-service equipment can be organised by sending a functional equipment on site and collecting the out-of-service equipment.

What is the difference between IT maintenance and outsourcing?

The difference between IT maintenance and outsourcing generally lies in the type of technical personnel involved. The word “maintenance” can sometimes be used to designate the activities of a company’s internal IT department. In this case, the latter is responsible for restoring the equipment to its original condition without the intervention of a third party.

Managed services” refers to the outsourcing of all or part of the company’s IT department. The company thus delegates the management of its equipment to a service provider. The latter then takes charge of all types of IT maintenance. It also offers all the levels of support detailed above, all within a commitment contract. In practice, a facilities management service can therefore include IS maintenance.

And at Codeo, what does IT maintenance mean?

Codeo has been an expert in IT asset maintenance for over 15 years. Our services are based on the following tools

  • remote technical support with a dedicated helpdesk, staffed by level 1 troubleshooting experts;
  • management of manufacturer’s warranty contracts to organise manufacturer’s returns, replacement equipment, removal of equipment
  • equipment repairs in technical workshops f

What are the Principles of Management?

The organisational principle is the great and overall direction for determining the performance. For instance, while ascertaining about the promotion of an employee, a manager may contemplate seniority, whereas the other may follow the principle of quality.
One may define principles of management from those of pure science. Management principles are not as firm as postulates of pure science. They deal with human traits and, hence, are to be employed creatively given the requirements of the position. Human behaviour is never inactive and so also technology, which business. Therefore all the principles have to keep step with these changes. For instance,

  • In the absenteeism of Information and Communications Technology (ICT), a manager could manage only a small workforce that too within a restricted geographical area.
  • The approach of ICT has developed the ability of the managers to control over large business domains scattered across the globe.
  • In promoting an understanding of the application of principles of management, it is also helpful to comprehend what these are not.
  • The principles of management should be selected from techniques of management. Techniques are methods or techniques, which include a group of steps to be taken to achieve sought goals.
  • Principles are guidelines to make judgements or actions while studying techniques. Moreover, principles should also be comprehended as being different from values.

Importance of Understanding Principles of Management:

(1) Providing Managers With Useful Insights Into Reality

  • The application of principles of management helps the managers to take right decisions at the right time.
  • These principles of management help managers to tackle the diverse problems in a dynamic business environment.

(2) Optimum Utilisation of Resources & Effective Administration

  • Resources are always scarce and limited.
  • By applying the management principles, the managers can focus on optimum use of available resources so as to achieve productive results at minimum cost and maximum profits.
  • It results in effective administration by channelising resources (human and material) into the best possible way.

(3) Scientific Decisions

  • Application of principles of management makes the manager more realistic, thoughtful, justifiable and free from personal bias.
  • The decisions taken on the basis of principles of management are subject to evaluation and objective assessment.

(4) Meeting Changing Business Environment

  • Although the principles are in the nature of general guidelines, they are modified and help managers to meet the changing requirements of the environment.

Example:

With the rapid rise of online market sellers, offline vendors have also started selling their goods on online platforms.

(5) Fulfilling Social Responsibility

  • Principles of management not only help in achieving the goals of the organisation effectively and efficiently, but they also guide the managers to fulfil their commitment towards its employees and society.

Example:

Principles of fair remuneration and equity ensure social justice to employees and compliance with government norms towards corporate social responsibility which improves the company’s image in the society.

(6) Management Training, Education and Research

  • Proper understanding of principles is the base of training, research and development in the field of management.
  • Management is taught on the basis of these principles, which help the management institutes prepare future managers.
  • These Principles help managers to take decisions and actions in the right manner.
  • Application of these principles by the managers brings innovation in the field of management.

Example:

It is the result of such training, education and research that Sunil Mittal could run Airtel in a successful way.

Features of Principles of Management:

(1) General Guidelines

  • The principles of management are just for a prescription.
  • They do not provide any ready-made solutions to all sorts of problems being faced by the organisations.
  • These can be modified as per the nature of the situation and human behaviour.

Example:

During the period of recession, the general manager may allow marketing departments to give away heavy discount to the customers without giving due attention to financial losses being raised by the financing department because the primacy of overall goals of the organisation is important.

(2) Universal Validity

  • Principles of management can be applied to any kind of organisation whether it is private or government, not for profit organisation, small, medium, large organisation etc.
  • But their applicability depends upon nature, size of the organisation and different situations.

Example: The whole work of an organisation is divided into smaller tasks, and such tasks are assigned to different departments, groups and individuals. Such a system of division of work is applicable in all types of organisations.

(3) Formed by Practice and Experimentation

  • The principles of management have been formed by experience and acquired the wisdom of managers over the years.

Example: Through collective practice, we can see that Fayol’s Principle-Discipline helps in increasing productivity.

Taylor’s Principle-Science, Not Rule of Thumb, brings out uniformity and standardisation in the manufacturing process of a company. ( we can give the same example which we have given in the case study because at this stage Fayol’s principle and Taylor principle are not yet discussed)

(4) Contingent

  • As the application of principles of management depends upon prevailing situations and needs, so their results may not be uniform as expected.

Example:

  • Remuneration of employees should be just and equitable, yet it may vary from person to person depending upon various situations.
  • Remuneration can be dependent on:
  • Industrial standard.
  • Employer’s paying capacity.
  • Contribution of employee etc.,

(5) Flexible

  • The principles of management are general prescriptions not rigid.
  • The managers can make certain changes as per the convenience and requirement of a situation.

Example:

Application of the principle of centralisation or decentralisation i.e. concentration or dispersal of authority to be delegated to employees depends upon the need, ability and competency of the employees. It also depends upon the nature of the organisation.

(6) Based on Cause and Effect

  • The principles of management are intended to establish cause and effect relationship so that the findings can be applied to such given situations frequently.
  • The principles of management tell the likely effect if a certain principle is applied.
  • The effect of such principles remains more or less the same due to their application on human behaviour.

Example:

By applying the principle of subordination of individual interest to the general interest, the behaviour of employees may be influenced in such a way that the personal goals of employees may be directed towards goals of the organisation.

(7) Mainly Behavioural

  • The principles of management aim at influencing the behaviour of employees.
  • With the help of principles of management, the managers try to bring desired changes in the behaviour of employees so as to achieve the organisational goals.

Example:

Orderliness decides behaviour among human beings in a company. Even the behaviour between men and machine can be decided by this principle of Management.

Difference Between Value and Principles of Management

database management system (DBMS)

What is a database management system?

A database management system (DBMS) is system software for creating and managing databases. A DBMS makes it possible for end users to create, protect, read, update and delete data in a database. The most prevalent type of data management platform, the DBMS essentially serves as an interface between databases and users or application programs, ensuring that data is consistently organized and remains easily accessible.

What does a DBMS do?

The DBMS manages the data; the database engine allows data to be accessed, locked and modified; and the database schema defines the database's logical structure. These three foundational elements help provide concurrency, security, data integrity and uniform data administration procedures. The DBMS supports many typical database administration tasks, including change management, performance monitoring and tuning, security, and backup and recovery. Most database management systems are also responsible for automated rollbacks and restarts as well as logging and auditing of activity in databases and the applications that access them.

The DBMS provides a centralized view of data that can be accessed by multiple users from multiple locations in a controlled manner. A DBMS can limit what data end users see and how they view the data, providing many views of a single database schema. End users and software programs are free from having to understand where the data is physically located or on what type of storage medium it resides because the DBMS handles all requests.

The DBMS can offer both logical and physical data independence to protect users and applications from having to know where data is stored or from being concerned about changes to the physical structure of data. So long as programs use the application programming interface (API) for the database that the DBMS provides, developers won't have to modify programs just because changes have been made to the database.
