Title: Wie eine Auswirkungsanalyse im Mainframe effizient und wirksam durchführt wird: Beispiele und Tipps

In today’s digital world, data analysis plays a pivotal role in decision-making and competitiveness for businesses. This is also true for Mainframe environments, where dealing with large volumes of complex data is the norm. In this article, we will explore how to conduct an efficient and effective Impact Analysis (IA) in Mainframe systems.

  1. Planning and Preparation
    "A good plan is the first requirement for making an excuse." (Thomas A. Edison)

    Planning and preparation are crucial for a successful IA. Identify the affected systems, prepare the necessary tools, and set up your environment accordingly.

  2. Comparing Data Before and After the Change
    "Comparisons reveal many truths." (Cicero)

    Compare data before and after the planned change. Graphs and tables are helpful in providing visual representations. For instance, by comparing CPU usage graphs or I/O statistics, you can determine the impact of changes on system performance.

  3. Automating and Utilizing Tools
    "Progress is the result of taking new steps." (Anonymous)

    Use automation tools and software to streamline the IA process. For example, IBM’s Control Desk can help monitor and analyze Mainframe environments. Similarly, using ITSM (IT Service Management) tools like ServiceNow or BMC Helix can provide valuable insights into system changes and their impact.

  4. Testing in Controlled Environments
    "Every great achievement was once considered impossible." (Robert H. Schuller)

    Test your changes in controlled environments to predict outcomes and minimize potential risks. For instance, you can perform testing in a development or test environment before deploying the change into production. This approach allows for a more comprehensive assessment of the impact and can help avoid any unintended consequences.

  5. Reviewing After Implementation


    "An error does not become a mistake until you refuse to correct it." (Chinese Proverb)

    After implementation, review the changes and rectify any issues that arise. This includes validating the correctness of data, checking for performance degradation, and ensuring system stability.

  6. Learning from Errors and Improvements
    "We learn something every day if we open ourselves up to it." (Carlos Ruiz Zafón)

    Reflect on the causes of errors and use these insights to improve your processes for a more efficient IA in the future. This can involve updating documentation, improving communication between teams, or fine-tuning automation tools.

**FAQs:**

  1. What is an Impact Analysis?
    An Impact Analysis (IA) is a process that examines the effects of a proposed change on a system. It identifies potential risks and helps minimize them by evaluating the impact of changes before they are implemented.

  2. Why is an Impact Analysis important?
    An Impact Analysis helps businesses make informed decisions, reduce risks, and improve competitiveness by understanding the consequences of their actions.

  3. What tools should I use for an Impact Analysis?
    Use automation tools and software like IBM’s Control Desk, ITSM tools such as ServiceNow or BMC Helix, and data comparison tools to streamline and enhance the Impact Analysis process.
