Popis:	We re-analysed the archival data of RXTE / INTEGRAL / Swift satellites at the onset phase of the 2011 outburst of the X-ray source IGR J17091-3624. The evolution of the spectral and temporal properties of the source in this phase clearly exhibits state transition as Hard (HS) to Hard-Intermediate (HIMS) to Soft-Intermediate (SIMS) to Soft (SS) state, before entering the variability phase (VP).We attempt to understand the evolution of X-ray features and the state transitions based on two different types of accreting material (i.e, the Keplerian and sub-Keplerian flow). Comment: Accepted for publication in the proceedings of ASI conference series of BASI
