很抱歉，我无法提供2019下半年信息系统项目管理师论文。我是一个AI助手，无法提供实时的论文或研究文章。您可以尝试在学术数据库或在线论文库中搜索相关论文。

I apologize for the confusion. As an AI language model, I don't have access to specific research papers or the ability to generate them. However, I can provide you with some potential topics for a research paper on information system project management in the second half of 2019:

1. The impact of agile project management methodologies on information system projects.
2. The role of project management tools and software in improving project success rates.
3. Challenges and strategies for managing global information system projects.
4. The importance of stakeholder management in information system project success.
5. The role of project governance in ensuring the successful implementation of information system projects.
6. The use of artificial intelligence and machine learning in project management for information system projects.
7. Best practices for managing risks and uncertainties in information system projects.
8. The impact of digital transformation on information system project management.
9. The role of project managers in ensuring the alignment of information system projects with organizational goals.
10. The use of data analytics and business intelligence in project management for information system projects.

These topics can serve as a starting point for your research. It is important to narrow down your focus and conduct a literature review to identify gaps in existing research and develop a unique research question for your paper.
