Final answer:
Juan Perez will primarily need to rely on conceptual skills to handle complex issues within WV Railroad involving the environment, government regulation, and competition, as these skills help in strategizing and understanding the interplay between different business areas and external pressures.
Step-by-step explanation:
Juan Perez, the President of WV Railroad, whose organization faces issues related to the environment, government regulation, and competition, will primarily need to rely on conceptual skills. These skills are vital for top-level management to navigate complex challenges, strategize, and understand how different parts of the business interact with one another and external factors. In the context of environmental issues, government regulations, and competition, conceptual skills are essential for creating long-term plans, making decisions that align with the company's values and goals, and remaining compliant with laws while also being competitive in the market.
In contrast, technical skills are more related to the specific knowledge required for particular tasks, while human skills involve the ability to manage and communicate with people effectively. Interpersonal skills could be beneficial as well, especially when dealing with government officials and negotiating with competitors, but they are not as pivotal as conceptual skills in this scenario. Lastly, controlling skills are important for ensuring that the strategies enacted are followed through, but the creation of these strategies is where conceptual skills shine.
