Current employment levels would be maintained, the statement said, and a new committee is being set up to look at "policies and processes for the design and development of the airplanes we build".
It has also brought uncomfortable scrutiny over new software, pilot training and regulatory rigour. At the same time, pilots will always be able to override MCAS and control the aircraft manually, Boeing says.
The software update, Boeing said in the statement, adds layers of protection and will stop erroneous data from activating the system.
"The potential of my sister and 156 others driven straight into the ground because of Boeing's greed", said Adnaan Stumo, Samya's brother.
The report contains flight data recorder information indicating the plane had an erroneous angle of attack sensor input that activated the manoeuvring characteristics augmentation system (MCAS) function during the flight.
Boeing's apology for the Ethiopian Airlines crash last month is "too little, too late", the pilot's father has told the BBC. Thursday's revelations raise questions about repeated assertions by Boeing and United States regulators that pilots could regain control in some emergencies by following steps that include turning off an anti-stall system designed specifically for the Max, known by its acronym, MCAS.

Announcing his decision to quit the Tory benches, Mr Boles said he would now sit as an independent progressive conservative. When MPs meet again on Wednesday "the United Kingdom has a last chance to break the deadlock or face the abyss ", he said.
A day earlier, the nation's transport minister called on Boeing to review the 737 Max flight-control system before allowing planes to be used, after a preliminary government report showing the doomed jetliner couldn't recover from an uncommanded and persistent nose dive shortly after takeoff.
Ethiopian Airlines has released a statement alongside the report which confirms that the crew complied fully with the correct operating procedures set for regaining control of the aircraft.
The Ethiopian investigators' preliminary findings put the embattled U.S. aviation giant under even greater pressure to restore clients' confidence and demonstrate the airworthiness of planes that crashed twice in less than five months. The plane made four nose dives before it crashed into the Java Sea.
"Aviation authorities shall verify that the review of the aircraft flight control system has been adequately addressed by the manufacturer before the release of the aircraft for operations", she added.
The pilots initially followed Boeing's emergency steps by disconnecting the MCAS system by switching off power to a stabiliser on the tail, the report said.
The report said that pilot-side sensor readings connected to the computer system varied wildly and affected everything from their understanding of the plane's pitch to its airspeed. For reasons that haven't been explained, they didn't try to also trim the plane using switches on their control yokes.
"With an MCAS failure such as they suffered, the nose pitching down radically multiple times would create literally the most hard situation I would imagine in an aircraft", pilot Anthony Roman told CBS correspondent Kris Van Cleave.
