An investment in education that enables you to accomplish an objective costs less money and more time; while implementation (e.g. executional services provided by someone experienced) will cost you less time and more money—typically differentiated by an 📝Order of Magnitude.
Investments in implementation will—in the best case scenario—only fulfill the specific need for which the service is contracted. Conversely, acquisition of education accumulates over time and fosters (a) intelligent hiring of contractors and consultants, (b) management of less experienced task-specific workers at lower cost, (c) and internal execution of previously outsourced tasks.
Investments in implementation are worthwhile when contracted for a one-time initiative, can be harvested for their process, or come with leverage (e.g. hiring a public relations agency that has strong contacts with journalists and members of the press that will speak about your project).
