Reports would be presented to the highest authorities, and frequently included the Politburo and Central Committee. At the other end Ordzhonikidze was sought out by factory managers, who would present grievances and petitions in hopes of getting help from Rabkrin. Ordzhonikidze revitalized Rabkrin; it became a powerful tool within the Soviet Union, and by the end of the 1920s was the centre of state industrial policy-making, usurping that role from Vesenkha. This role became more prominent during the first five-year plan, an economic development plan that began in 1929. While Vesenkha was tasked with implementing the high targets of the plan, Rabkrin oversaw everything and ensured that industrial production was increased while keeping costs down. This caused friction between the two bodies, Vesenkha complaining that they could not work with such interference, made worse by Rabkrin investigations of alleged wreckers and counter-revolutionaries. These disputes reached a peak at the 16th Party Congress in June 1930, where Ordzhonikidze gave a speech outlining Kuybyshev and Vesenkha's failures in industry. Vesenkha Likely in response to his critique of Kuybyshev, Ordzhonikidze was made the new head of Vesenkha on 13 November 1930, and Kuybyshev was moved to the State Planning Committee (Gosplan). Shortly after his new appointment, on 21 December 1930, Ordzhonikidze was also named as a full member of the Politburo, as he had also been removed from his post at the Central Control Commission. On his arrival at Vesenkha Ordzhonikidze was mandated to improve the quality of workers. Khlevniuk has also argued that by putting a close ally in charge of Vesenkha, Stalin was aiming to strengthen his own position in a field previously neglected. Replacing Ordzhonikidze at Rabkrin was Andrei Andreyev; with Stalin firmly in control of the Soviet Union, Rabkrin had lost its importance, and it was eventually made subordinate to the Central Committee. Much like when he started at Rabkrin, Ordzhonikidze was not an expert on the work of Vesenkha, but immediately began to familiarize himself with it. Though he was not educated, Ordzhonikidze compensated by being energetic and assertive in his tasks, and worked to deliver results. Devoted to his workers, he brought many of the senior staff from Rabkrin with him: by 1931 nine of eighteen sector heads in Vesenkha were either from Rabkrin or the
