Application Support: Setup, Team, Tools, and Approximate Costs

Application support - ScienceSoft

ScienceSoft provides application support and maintenance services since 2007.

Application Support: the Essence

Application support activities ensure maximized availability, complete and uninterrupted functioning, and sustained application evolution. The broad spectrum of app support measures can be loosely divided into two groups:

Reactive application support

  • Level 1: solving app usage issues and basic problems (help with logging in/out, password reset, etc.).
  • Level 2: fixing application operational issues without code changes (e.g., adding new columns to existing data sheets, improving configurations of platform-based applications).
  • Level 3: resolving complex problems by introducing changes to the code and database (e.g., for custom software – fixing defects on the code level, for platform-based apps – correcting issues with customizations).
  • Level 4: is applicable for platform-based apps only and is provided by software vendors (e.g., Microsoft, Salesforce, etc.).

Proactive application support (i.e., application maintenance)

  • Introducing new app features and integrations. For custom software - legacy code redesign or application restructuring/containerization.
  • Application performance monitoring and optimization.
  • CI/CD and DevOps implementation (to facilitate app updating, modernization or evolution).
  • Security code reviews and monitoring.
  • Exploratory and regression testing, testing of newly introduced features during the app’s evolution.
  • App infrastructure optimization (including cloud).

How to Set Up Application Support

The application support setup plan may vary depending the application’s scale, functionality and type (e.g., on-premises or cloud, customer- or employee-facing), support needs and requirements. Still, there are some common stages to go through.

Setup plan for application support - ScienceSoft

1. Estimate the scope of your application support

Duration: 1 week

Consider the following applications support factors:

  • The support scope and resources required depending on the application’s type. For example, customer-facing applications require more L1 support resources, while employee-facing ones are likely to generate a higher number of L2 and L3 requests.
  • Application support timeframes depending on the application’s criticality: e.g., business-critical applications like ERP requires 24/7/365 support.
  • Application’s age – legacy software may experience more issues and entail frequent fixes and updates.
  • Application performance requirements (e.g., the average and peak number of intended users, the average and peak load, scalability parameters) – applications with high performance requirements need continuous performance monitoring and recurring performance testing.
  • Number of integrations – more integrations imply more scenarios to monitor and more potential issues to resolve. Besides, after each substantial change in integrated software, you’ll need to validate data sharing between the systems, and run a regression test suite.
  • Standards and regulations your application should comply with (e.g., GDPR, HIPAA, PCI DSS). To stay compliant, you’ll need to design data protection policy and procedures for the support team; perform regular compliance checks, security code reviews, application security scanning, and tuning of cloud security components (if applicable).

2. Design the application support process

Duration: 4 weeks

Choose KPIs relevant for your application support needs. They may include:

Common metrics for reactive application support

  • First response time.
  • User satisfaction score.
  • Resolution rate.
  • Average time to resolution.

Common metrics for proactive application support

  • Application availability.
  • Application outage time.
  • Meant time to recovery.
  • Number of implemented change requests.
  • Number of change requests in the backlog.

Additionally, the progress of support activities can be tracked using general KPIs like the ratio between estimated and actual budget for the planned maintenance activity, its earned value and deadlines compliance.

After that, design ITSM-based standard operating procedures (SOPs) to stipulate all support and maintenance activities.

3. Prepare the application support

3.1. In-house application support

Duration: 4-12 weeks

Consider whether you have enough in-house resources to carry out the required support activities. You may need to train the current team members for them to get missing technical or soft skills and/or hire the required professionals.

Common support types and competencies required to perform them

  • Basic end user support - specialists with entry- or mid-level support experience having basic technical knowledge, good communication and conflict resolution skills.
  • Administrative support - specialists with senior- or mid-level experience in application administration and app monitoring, familiar with database querying.
  • Technical support and application evolution - software developers with mid-level or senior experience in software engineering, source code and database management.

Then, decide on a toolkit for your application support. It will be determined by the application type and needed support scope. For example, you may need:

For reactive application support

  • ITSM or ticket automation software.
  • Tools for communication between application users and app support agents (e.g., a customer portal, call center software, email clients, messengers like Microsoft Teams, Zoom, etc.).

For proactive application support

  • Continuous monitoring software for getting metrics on the overall application health, e.g., uptime and downtime, throughput, etc.
  • Application performance management (APM) software.
  • Code review tools.
  • Application security scanning software.
  • Cloud cost management tool.
  • Software testing frameworks and tools for automated API and UI regression testing.

3.2. Outsourced application support

Duration: about 12 weeks

To select an application support vendor:

  • Design a request for proposal (RFP) providing information on your application (type, architecture, technologies used, specific requirements) and needed IT application support scope.
  • Look for software support and/or development companies and check whether their human resources and tech stacks meet your application support demands.
  • Pay special attention to the certified partners of relevant platform providers and vendors holding such certificates as ISO 27001 and 9001 to be sure of the safety of your business information entrusted to the vendor and the overall quality of their services.
  • Shortlist 3-5 vendors with eligible competencies, resources, and recognitions.
  • Share your application support RFP with shortlisted vendors to get their cost estimation and support services proposal.

4. Launch your application support

Duration: up to 2 weeks

For the in-house option, your application support team should configure or customize the selected tools (e.g., for ITSM, continuous monitoring, application performance management, etc.) to meet your support needs.

With an outsourced application support option, at this stage you should:




Note: A service trial period may be handy to ensure the vendor’s services fully suit your application support needs and to fine-tune the SLA and KPIs.

With both outsourced and in-house support options, schedule the timeframes for planned activities preferably weekends or non-working hours). To ensure that app maintenance doesn’t cause work disruption, it’s better to inform users on upcoming activities.

Roles and Responsibilities within an Application Support Team

Application Support Costs

Application support costs may greatly differ with regard to the app’s type and requirements.

The most significant application support cost factor is the scope of support activities. Besides, you should mind the cost factors that are specific to the chosen sourcing model:

Application support outsourcing

  • Required response and resolution time depending on the app’s issues severity (e.g., up to 1-hour threshold for respond and 4 hours for the resolution of a critical issue).
  • The agreed and extra number of help desk tickets (for reactive application support outsourcing).
  • Support team composition and team members’ experience and competencies.

In-house application support

  • Application support staff costs.
  • Application support software licenses.
  • Cloud resources or hardware required to keep the application’s development, testing, staging, and production environment continuously available.

Typically, the cost of application support may be estimated as 15-25% of the initial development costs per year, while during the entire application lifespan it may comprise up to 70% of the total cost of ownership.

Here are the approximate estimations based on our application support experience for you to get a more precise picture of application support costs:

  • For a stable mid-size application with a small rate of minor change requests: $35,000/yr.
  • For a mid-size application that requires frequent and substantial changes: $80,000 - $160,000/yr.
  • For a complex enterprise application that require continuous evolution: from $200,000/yr.
