 Control totals are a method of verifying the accuracy and completeness of data processing by comparing the totals of key fields in input and output records1. Control totals can be used to reduce the risk of incomplete processing, which is the failure to process all the data or transactions that are expected or required2.

Incomplete processing can result in data loss, inconsistency, or incompleteness, which can affect the quality and reliability of the information system and its outputs. Incomplete processing can be caused by various factors, such as:

Hardware or software failures that interrupt the processing or transmission of data2

Human errors or omissions that skip or miss some data or transactions2

Malicious attacks or unauthorized access that delete or modify some data or transactions2

Environmental hazards or disasters that damage or destroy some data or transactions2

Control totals can help detect and prevent incomplete processing by:

Providing a benchmark or reference point to compare the input and output data or transactions1

Identifying any discrepancies or deviations from the expected or required totals1

Alerting the users or operators to investigate and resolve the causes of incomplete processing1

Ensuring that all the data or transactions are properly transmitted, converted, and processed1

The other options are not as relevant as control totals for reducing the risk of incomplete processing. Posting to the wrong record is the error of assigning or transferring data or transactions to an incorrect account, file, or record3. Improper backup is the failure to create, store, or restore copies of data or transactions in case of loss, corruption, or damage4. Improper authorization is the lack of proper permission or approval to access, modify,or process data or transactions. Control totals may not be able to prevent or detect these errors or failures, as they are not related to the completeness of data processing. Therefore, option B is the correct answer.

Aligning IT strategy with business strategy primarily helps an organization to optimize investments in IT. This is because alignment ensures that IT resources and capabilities are aligned with the business goals and priorities, and that IT delivers value to the business in terms of efficiency, effectiveness, innovation, and competitive advantage12. By aligning IT strategy with business strategy, an organization can avoid wasting money and time on IT projects or services that do not support or contribute to the business outcomes3. Alignment also helps to identify and prioritize the most critical and valuable IT initiatives that can create or optimize business value4.

Therefore, the correct answer to your question is A. optimize investments in IT.

Validation checks are a type of data quality control that helps to ensure the integrity of data for a system interface. Validation checks verify that the data entered or transferred between systems is correct, consistent, and conforms to predefined rules or standards. Validation checks can prevent or detect errors, anomalies, or inconsistencies in the data that may affect the system’s functionality, performance, or security.

Option C is correct because validation checks are a common and effective method of ensuring data integrity for a system interface. Validation checks can be performed at various stages of the data lifecycle, such as input, processing, output, or storage. Validation checks can also be applied to different types of data, such as data types, codes, ranges, formats, consistency, and uniqueness.

Option A is incorrect because system interface testing is a type of software testing that verifies the interaction between two separate systems or components of a system. System interface testing does not directly ensure the integrity of data for a system interface, but rather the functionality and reliability of the interface itself. System interface testing may use validation checks as part of its test cases, but it is not the same as validation checks.

Option B is incorrect because user acceptance testing (UAT) is a type of software testing that evaluates whether the system meets the user’s expectations and requirements. UAT does not directly ensure the integrity of data for a system interface, but rather the usability and acceptability of the system from the user’s perspective. UAT may use validation checks as part of its test scenarios, but it is not the same as validation checks.

Option D is incorrect because audit logs are records of events and activities that occur within a system or network. Audit logs do not directly ensure the integrity of data for a system interface, but rather provide evidence and accountability for the system’s operations and security. Audit logs may use validation checks as part of their analysis or reporting, but they are not the same as validation checks.

The best recommendation to address the problem of missing IT deadlines on important projects because IT resources are not prioritized properly is to implement project portfolio management (PPM). PPM is the process of analyzing and optimizing the costs, resources, technologies, and processes for all the projects and programs within a portfolio. A portfolio is a collection of projects, programs, and processes that are managed together and aligned with the strategic goals and objectives of the organization. PPM can help the organization to:

Prioritize the most valuable and relevant projects and programs based on their alignment with the organizational strategy, vision, and mission.

Balance the portfolio to ensure that the projects and programs are diversified, feasible, and sustainable, and that they meet the needs and expectations of the stakeholders.

Optimize the allocation, utilization, and coordination of IT resources across the portfolio, such as staff, budget, time, equipment, and software.

Monitor and control the performance and progress of the projects and programs within the portfolio, and evaluate their outcomes and benefits.

By implementing PPM, the organization can improve its IT project delivery and avoid missing deadlines. PPM can also help the organization to increase its efficiency, effectiveness, quality, and value. For more information about PPM, you can refer to the following web search results:
