In this blog post, we’ll explore how measuring and monitoring metrics related to software testing environments can greatly benefit Value Stream Mapping (VSM) efforts. These metrics may encompass factors such as test coverage, defect density, and resource utilization. By gathering and analyzing this data, organizations can enhance their testing processes, identify areas that require improvement, and ultimately deliver higher-quality software. Moreover, we’ll provide examples of specific metrics to track, along with suggestions for tools that can be utilized to gather and analyze the relevant data.

What is VSM

Value Stream Mapping (VSM) is a lean manufacturing technique used to analyze and improve the flow of materials and information required to produce a product or service. It is a visual tool that helps organizations to map out their current state of production, identify inefficiencies, and design a more efficient future state. VSM is used across a variety of industries, including software development, to optimize processes and eliminate waste, ultimately improving productivity, quality, and customer satisfaction.

In software development, Value Stream Mapping (VSM) is used to analyze the flow of work from idea to delivery, identifying areas where delays, inefficiencies, and waste occur. By mapping out the current state of software development and identifying areas for improvement, teams can optimize their workflows, reduce cycle times, and improve the overall quality of their software products. VSM can help teams to focus on delivering value to customers by eliminating waste, improving communication, and streamlining processes. This leads to faster delivery of high-quality software, increased customer satisfaction, and ultimately, a more successful software development process.

Metrics & VSM

Metrics support Value Stream Mapping (VSM) by providing valuable insights into the performance of various processes and activities involved in software testing. By tracking metrics related to test coverage, defect density, resource utilization, and other factors, organizations can identify bottlenecks and inefficiencies in their testing processes, and make data-driven decisions to optimize and streamline their workflows. This, in turn, can lead to improved overall efficiency, reduced costs, and faster delivery of high-quality software products, all of which contribute to a successful VSM strategy.

TEM METRICS – Test Environment Metrics

Preamble: A key component of Test Environment Management is the ongoing measurement and optimization of your TEM practices. Below, is a list of metrics that should be captured as part of establishing Test Environment Management capability.

Note: These are not exhaustive, however capturing this information will set you on your way to implementing a successful TEM services organisation.

Test Environment Metrics:

Environment Coverage

    • % of Test Environment Systems (Instances) under management (within CMDB)
    • % of Test Environment Systems (Instances) with rich knowledge (IP) attached

Environment Usage

    • Historical Usage of Test Environment Systems (Instances)
    • Future (Planned) Usage of Test Environment Systems (Instances)

Environment Agility

    • Time to Set Up an E2E Environment
    • Time to Setup Systems (Instances)

Environment Availability

    • Availability of Environment
    • Availability of Systems (Instances)

Operational Metrics – Change

    • Number of System Changes
    • Outage caused by Change
    • % of Failed vs Successful Changes
    • % of Tasks Automated vs Manual

Operational Metrics – Release

    • Number of System Releases
    • Outage caused by Release
    • % of Failed vs Successful Releases
    • % of Tasks Automated vs Manual

Operational Metrics – Data Refresh

    • Number of System Data Refreshes
    • Time to do a Data Refresh
    • % of Failed vs Successful Data Refresh’s
    • % of Tasks Automated vs Manual

Conclusion

In summary, Test Environment Metrics are crucial for building a successful Test Environment Management capability, which is an essential component of Value Stream Mapping (VSM). Effective metrics offer valuable insights into the coverage, usage, agility, availability, and operational performance of the test environment. By capturing and analyzing this data, organizations can optimize their test environment for maximum efficiency and reliability, thereby supporting their VSM efforts.
