For the past five months, a small committee of Boeing’s board has been interviewing company employees, safety experts and executives at other industrial organizations in an attempt to understand how the aerospace giant could design and build safer airplanes.

The committee is expected to deliver its findings to the full Boeing board this week, and call for several meaningful changes to the way the company is structured, according to three people briefed on the matter who spoke on the condition of anonymity because the report has not yet been submitted.

The recommendations will include that Boeing change aspects of its organizational structure, calling for the creation of new groups focused on safety and encouraging the company to consider making changes to the cockpits of future airplanes to accommodate a new generation of pilots, some of whom may have less training.

Though the committee did not investigate the two crashes of Boeing’s 737 Max jet, their findings represent the company’s most direct effort yet to reform its internal processes after the accidents, which killed 346 people.
