I keep an Excel control table. Every task assigned goes on that table with a project, type (report, code, algorithm design or integration work) and module (which part of the project needs an update). There is also a remark column which I one day intend to process with nlp. I also like to generate a pivot table at the end of each week to know which type or modules of work I'm neglecting. I've also got some conditional formatting to mark rows as red when I blow the deadline (red) or when I need to finish something by today (yellow). Has worked well for me when I was an engineer and I'm evaluating this work flow for an integrator (it's an official post for someone who makes sure that several teams deliver compatible outputs on time).
