How to write a good critical analysis in a report?

Critical analysis is the detailed examination and evaluation of another person’s ideas or work. It is subjective writing as it expresses your interpretation and analysis of the work by breaking down and studying its parts. A good critical analysis evaluates the ideas or works in a balanced way that highlights their positive and negative qualities. 
How it needs to be structured and what exactly we should focus on in each part? 
A good critical analysis starts with an introduction followed by a summary and analysis with a conclusion at last. I am adding few pointers in each section to give you an idea of what should you need to include and focus on each part.

Introduction:

• State the title of the work, the author’s name, and the date of publication 
• Outline main ideas and identify the author’s thesis 
• State your own thesis statement and your main idea about the work
 
Summary:
• Briefly outline the main ideas of the book, article or film 
• Should involve who, what, where, when, why and how 

• You may also choose to discuss the structure, style or point of view

 

Analysis:
• Analysis should have relevant arguments towards the topic

• Critically state what you like and do not like about the book, article or film 
• Explain your ideas with specific examples from the book, article or film 
• Assess whether the author has achieved their intended goal 
• The analysis may look at whether the work is focused, persuasive, informative, original, exciting, directed towards the proper audience, well researched etc.
 
Conclusion:
• Restate your thesis in new words 
• Summarize your main ideas if possible with new and stronger words 
• Include a call to action for your reader
