You are AuditQ&A, an AI Assistant created by Auditors and Data Scientist. You are given a question and extracted passages of the consolidated/departmental/thematic focus audit reports. Provide a clear and structured answer based on the passages/context provided and the guidelines.
Guidelines:
- If the passages have useful facts or numbers, use them in your answer.
- When you use information from a passage, mention where it came from by using [Doc i] at the end of the sentence. i stands for the number of the document.
- Do not use the sentence 'Doc i says ...' to say where information came from.
- If the same thing is said in more than one document, you can mention all of them like this: [Doc i, Doc j, Doc k]
- Do not just summarize each passage one by one. Group your summaries to highlight the key parts in the explanation.
- If it makes sense, use bullet points and lists to make your answers easier to understand.
- You do not need to use every passage. Only use the ones that help answer the question.
- If the documents do not have the information needed to answer the question, just say you do not have enough information.

consistent with the mandate of Supreme Audit Institutions (SAIs),\
remains integral in ensuring transparency and fiscal responsibility.\
Regularly, the OAG submits comprehensive audit reports to Parliament, \
which serve as instrumental references for both policymakers and the public, \
facilitating informed decisions regarding public expenditure.
However, the prevalent underutilization of these audit reports, \
leading to numerous unimplemented recommendations, has posed significant challenges\
to the effectiveness and impact of the OAG's operations. The audit reports made available \
to the public have not been effectively used by them and other relevant stakeholders. \
The current format of the audit reports is considered a challenge to the \
stakeholders' accessibility and usability. This in one way constrains transparency \
and accountability in the utilization of public funds and effective service delivery.
In the face of this, modern advancements in Artificial Intelligence (AI),\
particularly Retrieval Augmented Generation (RAG) technology, \
emerge as a promising solution. By harnessing the capabilities of such AI tools, \
there is an opportunity not only to improve the accessibility and understanding \
of these audit reports but also to ensure that their insights are effectively \
translated into actionable outcomes, thereby reinforcing public transparency \
and service delivery in Uganda.
To address these issues, the OAG has initiated several projects, \
such as the Audit Recommendation Tracking (ART) System and the Citizens Feedback Platform (CFP). \
These systems are designed to increase the transparency and relevance of audit activities. \
However, despite these efforts, engagement and awareness of the audit findings remain low, \
and the complexity of the information often hinders effective public utilization. Recognizing the need for further\
enhancement in how audit reports are processed and understood, \
the **Civil Society and Budget Advocacy Group (CSBAG)** in partnership with the **GIZ**, \
has recognizing the need for further enhancement in how audit reports are processed and understood.
This prototype tool leveraging AI (Artificial Intelligence) aims at offering critical capabilities such as '
summarizing complex texts, extracting thematic insights, and enabling interactive, \
user-friendly analysis through a chatbot interface. By making the audit reports more accessible,\
this aims to increase readership and utilization among stakeholders, \
which can lead to better accountability and improve service delivery
