How much time does each stage of paper in Elsevier Editorial System (EES) take? We have submitted a paper to an Elsevier Journal and now I want to know how much time each stage in article lifecycle take?

There is an article in Elsevier site which describes different status of a paper from submission to publication:


Submitted to Journal
Editor Invited (Conditional - this step may not occurs)
With Editor
Under Review
Required Reviews Complete
Decision in Process
Completed – Accept


It also noted that:


  Please Note: Most journals aim to communicate decisions to authors within four months of the start of the review process. There are a number of factors that may influence the actual time taken, most notably the availability and responsiveness of the article's referees. In consequence, peer review times do vary per journal. During the peer review process your article will show a status of ‘Under Review’.


But our paper status is Technical Check In Progress. this status is not mentioned in Elsevier site! I'm confused about this statuses. and now after 40 days the status is still in that stage. I want an estimation about time of this steps to see if I should be concern or not.
Each electronic manuscript handling system typically has a set time frame for each part of the review-revisions process. The systems have default values which, I would assume, are what most journals use. It is, however, possible to custom make the different time periods for each part of the process.

1.Submitted to Journal:
This usually does not involve a lot of time and a reasonable time frame might be 5-10 days depending on factors such as workload, time of year etc. The step might involve inspection of the quality of the submitted material, but not necessarily.

2.Editor Invited (Conditional - this step may not occur):
This may again be another 5-10 days and may be affected by workload etc.

3.With Editor:
The main problem that occurs here is difficulty to assign reviewers. The editor may also be overloaded with work. The time frame is likely something like 3 weeks but will vary.

4.Under Review:
Each journal has a time frame and  3 weeks is what I am accustomed to in my field. Reviewers that accept reviews and never return them is a problem here. How quickly the editor tries to assign other reviewers to speed up the process will vary from person to person and journal to journal.

5.Required Reviews Complete:
I am not sure if you actually mean revisions here because typically the author gets about 3-6 weeks to revise the manuscript. This is another point where delays can occur but they are self-inflicted.

6.Decision in Process:
The decision process may require some time since the editor needs to read the revised manuscript and the revisions/rebuttal from the author to make a decision. In many cases there is cause for another round of reviews which would loop back to 4 and 5.

7.Completed – Accept:
7 could be 6 if the manuscript gets accepted after one round (rare in many circumstances).

Once accepted, the manuscript goes to copy editing and type-setting. This may be a quick process depending on the resources provided by the publisher. Journals using LaTeX have the advantage of having print ready proofs basically at the turn of a switch.

To sum up. Each of these steps can take various amounts of time depending on the working conditions at the journal as well as the expedience of reviewers and authors. I think the time frames I have outlined are reasonable but that does not mean all journals will be that quick (or slow, depending on your view).
