Once you have defined your maturity levels, you need to communicate your vision and benefits to your stakeholders, such as senior management, business units, IT staff, and customers. You need to explain why IT strategy maturity is important, how it supports your business strategy, and what benefits it will bring to each stakeholder group. You can use various methods, such as presentations, reports, newsletters, workshops, or webinars, to convey your message and engage your audience. You should also provide regular updates on your progress and achievements, and celebrate your milestones and successes.
