The article discusses methodologies that allow to describe and visualize various business processes, their study and obtaining answers to questions of interest. This is necessary for a visual representation of technological processes and the search for ways to increase their efficiency. For the successful implementation of information systems, the design model must be carefully described; information models of information systems must be built. Without the use of any information technology, the design of objects is carried out on an intuitive level, using practical design skills. Using the methods of visual presentation of information, give a visual representation of the information modeling of the workstation of a sawmill technologist. This involves the construction of structural diagrams, the ability to build diagrams using color schemes, diagrams allow you to test at different levels and determine cyclic elements. CASE-technologies allow you to quickly and clearly develop an information model of any complexity and any depth of detail of the project. CASE tools for developing an information model apply diagrams at various levels. Information modeling of the automated workplace of a sawmill technologist is intended to carry out a set of measures aimed at organizing the technological process of a sawmill for the production of edged and unedged sawn timber.
