I have reviewed a lot of SMS and finally decided on Mango, the main reason was it is intuitive, it manages all HSEQ and training, the field guys can use the app to load events, conduct audits, raise improvements etc in the field, also has the ability to align with ISO standards, the auditing tool is also very useful in the field. Highly recommend it, i have used the vault also but would rate Mango as a better product.
