Technical support in software engineering is typically organized into three tiers: L1 (Level 1), L2 (Level 2), and L3 (Level 3). This hierarchical structure ensures efficient problem-solving and customer service for various software issues. Each level represents a different degree of technical expertise and problem complexity.

L1 support is the first line of contact for end-users, handling basic troubleshooting and common issues. L2 support deals with more complex problems that require deeper technical knowledge. L3 support is the highest tier, involving expert engineers who tackle the most challenging and critical issues in the software.

L1 Technical Support

1. Responsibilities

L1 Technical Support is also known as first-line, first-level support. It entails providing the first point of contact for users of a firm’s software products when they get stuck or have an issue to deal with about the software products. The primary responsibilities of L1 support technicians include:

• Receiving and Logging Requests: Receiving support requests in the form of a call, when the management of information security empowers the customer with a new password for his or her account, responding to email inquiries.
• Basic Troubleshooting: As soon as ordinary problems like password restoration, installation of a new program, or configuration problems occur, the help of a computer technician is required.
• Knowledge Base Utilization: Diagnosis of cases tuning to the knowledge base of the specific solutions.
• Ticket Escalation: In a case where there are outstanding problems that cannot be solved under L1 support the problems should be escalated to the next level of support – L2.
• Customer Communication: Creating and providing simple client relations that will create awareness for the customers so that they can understand and be satisfied.

L1 technicians are not expected to perform comprehensive technical problem-solving, and the behavior is guided by the referred scripts or guidelines. It operates only for an early and immediate resolution of a simple matter so that the higher level technicians have an opportunity and time to work out some other complex ones.

2. Skills Required

• Communication Skills: Good interpersonal skills so as to communicate verbally and in writing to the customers.
• Basic Software Knowledge: Familiarity with the software applications and some level of problem solving skills.
• Problem-Solving Abilities: Ability to recognize some problems in relative short period of time and offer clear and easy solutions.
• Helpdesk Tools: Helpdesk experience with different software and operating a ticketing system.
• Customer Service Orientation: Focus on number of factors that revolve around the provision of customer services and customer satisfaction.

3. Typical Issues Handled

• Password Resets: Helping the users to Reset /Recover his/her password .
• Basic Installations: Assisting the clients in installation of the software and initial setting up of the systems.
• Usage Inquiries: Answering general questions concerning how the software works and general questions about certain operations.
• Account Management: Managing of user accounts/permissions.
• Connectivity Issues: Basic network issue such as Wi-Fi connectivity.

4. Salaries

• Entry-Level: The pay scale for entry-level L1 technicians is at a minimum of Rs.35,000 for the initial year of employment.
• Experienced Technicians: The salary can be as low as Rs.30,000 per year, the ones with an extensive experience may receive as much as Rs.50000 per year.
• Industry Variance: Industry variations can also be seen in relation to the salary as well as geographical location differences.
• Benefits: These often form part of a package for example- health care benefits, retirement and pension, and vacation allowances.

L2 Technical Support

1. Responsibilities

L2 Technical Support is a more advanced level of support that ranges from issues that first-level support or L1 cannot handle. The primary responsibilities of L2 support technicians include:

• Advanced Troubleshooting: They are loaded with additional issues that require problem-solving capacity and technicality in tackling requests.
• Problem Analysis: Rather than dealing with symptoms of problems, get to the root of issues and solve them.
• Guidance to L1 Support: Training and support to the L1 technicians and development of technical guidance in the form of manuals and other documentation.
• System and Software Configuration: Advanced management of operating system and system-level diagnostics.
• Escalation to L3: If several incidences remain outside the L2 span of responsibility, which encompasses code changes then they must be forwarded to the L3.

L2 technicians have a better perception of the software in question and the conditions that such software has to operate under. They might also have experience in scripting and that little bit of coding that is often required in the correction of error messages.

2. Skills Required

• Technical Competency: General knowledge about the software and the current environment.
• Analytical Thinking: Skills in analysis of issues so as to determine the cause closest to the root cause of the concern.
• Advanced Troubleshooting: Problem solving skills which enable one to diagnose hard problems and find solutions.
• Interpersonal Skills: Communication/collaboration to convey detailed info to the users and L1 technicians.
• Documentation Skills: The technical capacity to write technical manuals and consequently user manuals.

3. Typical Issues Handled

• System Errors: Handling application and other system level errors that need more analysis.
• Performance Issues: Analyzing and diagnosing all performance related issues that may be affecting the organizations.
• Intermediate Networking: Diagnosing functional network problems and security settings.
• Software Updates: Delivering and setting up new software version, and patching.
• Guidance to L1 Support: Training and enhancing facilitation of the L1 technicians.

4. Salaries

• Base Salary: The L2 support technicians are paid an average salary ranging from Rs.50000 to Rs.60000 in a year.
• Experience-Based: Technicians with more counter experience can receive up to Rs.75,000 per year.
• Industry Differences: Working hours get determined by the industry and the specifications of the systems that they deal with.
• Additional Benefits: Sometimes may cover health insurance, bonus pay and other such things as staff development.

L3 Technical Support

1. Responsibilities

L3 Technical Support goes by different names, and among them are L3 technical support or third-level support, It deals with issues that cannot be solved by any L1 or L2 technician. The primary responsibilities of L3 support technicians include:

• Deep Technical Analysis: A problem-solving process in the software base when the formation of hypotheses and deep analyses of various issues take place.
• Bug Fixing: Updating to change the script as a way of fixing software problems and implementing a patch or an update.
• Performance Tuning: A main set of tasks, concerning the definition of the basic parameters of software and its effective operation.
• Collaboration with Development Teams: Interacting with developers in establishing the cause of a certain issue and at the same time, trying to locate a permanent fix.
• Proactive Problem Prevention: Understanding methodological recommendations for the formation of undesirable trends, and combating them.

L3 technicians are usually experienced software engineers of appropriate levels who understand the process of creating software products and who possess good system analysis and design skills. They have a considerable degree of awareness about the program code and the general organization of the network.
