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:
