Script Execution Schedule for SaaS Extension Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In software platforms with extensible extension points, the execution of multiple scripts at a single point is unclear, leading to unpredictable system behavior and undesired results due to lack of a systematic approach for ordering and combining script outputs.
Innovation Solution
A framework is provided for determining a script execution schedule that considers scheduling parameters such as enable/disable parameters, sequence of execution, and interdependency, allowing for independent or dependent execution of scripts, with output rules to combine results effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple scripts are executed at a single extension point without a systematic scheduling approach, then the platform maintains simplicity and ease of operation, but the system behavior becomes unpredictable and produces undesired results
Solution Approach 1:
The system performs preliminary actions by determining a script execution schedule before actually executing the scripts. This schedule specifies the order of execution and how inputs/outputs are obtained, ensuring predictable system behavior while maintaining manageable complexity through advance planning
Solution Approach 2:
The system implements dynamic execution modes where scripts can be executed independently with the same inputs or in sequence where output of one becomes input of another. The execution schedule adapts to different scenarios, providing flexibility while maintaining predictability through defined rules
2Adaptability or versatility
If scripts are executed independently with the same inputs, then the execution management remains simple, but the functionality and customization capability are limited
Solution Approach 1:
The system provides dynamic execution modes that can switch between independent parallel execution and dependent sequential execution. This allows the platform to adapt to different functional requirements while managing complexity through a unified scheduling framework that handles both modes
Solution Approach 2:
The execution schedule framework serves multiple functions: it manages independent script execution, manages dependent script execution with output-as-input, and provides a unified interface for both scenarios. This multi-functionality increases adaptability without proportionally increasing complexity
3Reliability
If a systematic script execution schedule is implemented, then predictable system behavior is achieved, but the platform complexity increases
Solution Approach 1:
By determining the execution schedule in advance before script execution, the system ensures consistent and predictable behavior. The schedule is established once and then followed during execution, maintaining reliability while keeping the actual execution phase simple and straightforward
Solution Approach 2:
The system applies output rules that determine how script outputs are combined or selected to produce an overall output. This feedback mechanism ensures consistency by systematically processing individual script outputs according to predefined rules, maintaining reliability without requiring complex real-time decision-making

AI summary
Systems and methods of executing multiple scripts at an extension point are provided. If there are multiple scripts that are associated with an extension point for a service instance in a SAAS platform, a script execution schedule is determined. This can indicate the order of execution of the multiple scripts, but may also specify how the inputs and outputs of the multiple script executions are obtained. For example, the inputs for multiple scripts can be the same, and be those provided by the SAAS platform at the extension point. In this case, in effect the multiple scripts are executed independently. Alternatively, the output of one script can function as the input to another script, which requires a certain order of execution. After all of the scripts are executed, output rules are used to determine an overall output of the script execution to be returned the platform through the extension point.
