Articles in headings and lists

Hello,

Writing a technical description of a software, I need to make a lot of sections, subsections and paragraphs, each of which needs to have a heading of their own.

In addition, there have to be a lot of lists showing various features of that software.

Do I have to use articles in the headings and/or lists, or can they be elided?

An example:

Main benefits

• greater transparency of company activities,
• relevant data for decision-making,
• an increase in labour productivity,
• a reduction of cost,
• a higher level of data security,
• an increase in the reliability of production processes or in the quality of production,
• effective evaluation of a company’s activities, and controlling.

When - if ever - can I omit articles?

Many thanks for your comments!
